Sump Pump Installation

Sump Pump Installation

The purpose of a sump pump is to help drain water away from a foundation. The sump pump basin allows the water to collect, then the sump pump discharges the water out either to a dry well, storm drain or most commonly above grade routed away from the building. One of the common reasons.

Identify Your Foundation Issue

Not sure what's wrong? Match your crack to the descriptions below to find the right solution.

Vertical Cracks

Look: A straight up-and-down crack.

Common In: Poured concrete homes in Mississauga & Brampton.

Cause: Concrete shrinkage or minor settling.

The Fix: Polyurethane Crack Injection

Horizontal Cracks

Look: A crack running sideways across the wall.

Common In: Block foundations or older concrete.

Cause: Heavy soil pressure pushing the wall inward.

The Fix: Structural Exterior Waterproofing (Urgent).

Step-Cracks

Look: A "staircase" pattern along mortar lines.

Common In: Brick or cinder block homes in Toronto.

Cause: Foundation settling or sinking footing.

The Fix: Foundation Underpinning or Stabilization.

Floor-Wall Joint (Cove)

Look: Water seeping where the wall meets the floor.

Common In: High water tables (Hamilton/Niagara).

Cause: Hydrostatic pressure under the slab.

The Fix: Interior Weeping Tile System

The Anatomy of a Waterproofed Foundation

We don't just "patch" leaks. We install a 5-layer engineered system designed to manage Southern Ontario's heavy soil conditions.

Layer 1: The Seal

Rubberized Bitumen

We apply a heavy-duty, rubberized membrane directly to the bare foundation wall. This seals all pores, hairline cracks, and imperfections.

Layer 2: The Shield

Dimple Board (Delta-MS)

This tough plastic sheet creates an "air gap" against the wall. If water hits it, it flows straight down to the drain without touching the concrete.

Layer 4: The Filter

¾" Clear Gravel

We backfill the trench with clean gravel, not dirt. This acts as a massive filter, allowing water to drain instantly rather than pooling against the wall.

Layer 5: The Exit

Weeping Tile

A perforated pipe at the footing collects the water from the gravel and routes it safely away to a sump pump or storm sewer.

We Know Your Home's Unique Anatomy

Every era of home building in Southern Ontario requires a different waterproofing approach.

  • 🏚️ Historic & Victorian Homes (Pre-1940s)
    Common in Downtown Toronto & Hamilton. We specialize in treating crumbling stone foundations and restoring century-old brick mortar that standard injections cannot fix.
  • 🏠 Post-War Bungalows (1950s-70s)
    Common in Etobicoke, North York & Scarborough. These block-foundation homes are prone to "step cracks" and weeping tile failure. We restore them to modern dry standards.
  • 🏘️ Modern Subdivisions (1990s-Present)
    Common in Vaughan, Markham & Durham. Poured concrete foundations often suffer from shrinkage cracks and rod-hole leaks. We offer fast, minimally invasive injections.
  • 🌲 Cottages & Chalets
    Common in Muskoka, Collingwood & The Highlands. We engineer drainage solutions that specifically handle granite bedrock run-off and heavy spring snowmelt.

A Smart Investment for Home Resale

A wet basement can lower your property value by up to 15%. Dryshield doesn't just fix the leak; we provide a Lifetime Transferable Warranty.

This means if you sell your house, the warranty moves to the new owner. In the competitive Southern Ontario real estate market, a Dryshield Certificate is a valuable selling feature that gives buyers peace of mind.

🛑 "Can I just use waterproof paint?" (The DIY Myth)

We get asked this every day. Here is the honest truth about DIY solutions.

The DIY Approach (Sealant Paint)

What it does: Acts like a thin layer of "skin" on the inside of your wall.

The Problem: Hydrostatic pressure from the soil is powerful (thousands of pounds). It will eventually bubble, peel, and push right through the paint because the water is still trapped inside the concrete.

Result: Temporary fix (6-12 months).

The Dryshield Approach (Drainage)

What it does: Relieves the pressure completely. We install a membrane that guides water down into a weeping tile and out via a pump.

The Solution: We don't just block the water; we give it a path to escape so it never touches your floor.

Result: Permanent solution (Lifetime Warranty).

Why Basements Leak in Toronto & Southern Ontario

Homes in our service area face unique challenges based on local geology:

The GTA & Golden Horseshoe (Clay):

  • The dense clay soil in Toronto, Peel, and Hamilton absorbs water like a sponge. When it expands, it pushes against your foundation (Hydrostatic Pressure), causing cracks.

Muskoka & The Highlands (Granite):

  • Cottages built on the Canadian Shield often face water running along the bedrock surface and pooling against the foundation, especially during the spring melt.

The Freeze-Thaw Cycle:

  • In Southern Ontario, wet soil freezes and expands in winter. This movement can shift foundation walls and create new entry points for water every single year.

Waterproofing Glossary: Terms You Should Know

  • Hydrostatic Pressure: The force exerted by standing groundwater against your foundation walls. This is the #1 cause of basement leaks in Mississauga, Brampton, and Clay-Soil areas.

  • Efflorescence: A white, chalky powder found on basement walls. It is caused by water evaporating through the concrete, leaving salt deposits behind—a sure sign of slow seepage.

  • Weeping Tile: A perforated drainage pipe installed at the base of your footing (interior or exterior) to collect groundwater and divert it to a sump pump or storm sewer.

  • Parging: The decorative cement coating on the visible, above-grade portion of your foundation. While it looks nice, parging does not waterproof your basement.

  • Cold Joint: The seam where the foundation wall meets the floor footing. This is the most common entry point for water in older homes in Toronto and Hamilton.

FREQUENTLY ASKED QUESTIONS

Waterproofing is a technique used to keep water from infiltrating your basement foundation, even during heavy rainstorms or seasonal thaws. When Dryshield Waterproofing experts complete the process, you can be confident that your basement will remain dry and functional, just like any other part of your home.

The cost of professional basement waterproofing can range from a few hundred dollars for minor fixes to several thousand dollars for more extensive solutions. While the upfront cost may seem significant, investing in basement waterproofing protects your home from costly water damage and can increase its market value. Homes with documented, warrantied waterproofing tend to sell faster and at higher prices.

For the most accurate pricing and a customized solution, we offer free basement waterproofing estimates from our Dryshield waterproofing professionals. Contact us today at 1.800.277.5411 to learn more about our services and find the best, cost-effective option for your home.

The lifespan of basement waterproofing depends on the method used and the quality of installation. Interior waterproofing solutions with sump pumps are lifetime warrantied sump pumps that come with a 2- 3 year manufacturer warranty and can need replacing sooner. Typically industrial cas iron sump pumps will last 5 to 8 years on average depending on how much water is pumped over a period of time. Exterior waterproofing will typically last the lifespan of your foundation if done properly when the highest quality materials are used. However homeowners need to be aware that if water comes up from underneath the floor eternal waterproofing will not protect the foundation from seepage. With professional installation and proper maintenance, most waterproofing solutions will provide lifetime protection. At Dryshield, we only use high-quality materials and expert techniques to ensure a lifetime guaranteed results. We are proud to offer a lifetime guarantee on all our waterproofing services.

A musty smell in your basement typically signals dampness, even if no visible water leaks may be present or mold may be growing if there is high enough relative humidity. An odor is often caused by mold or mildew, which thrive in moist environments and can trigger health problems like asthma and allergies. Dryshield Waterproofing offers effective solutions to eliminate the moisture causing the smell, sealing your basement’s walls and floors and creating a dry, fresh environment.

Exterior waterproofing is the most reliable solution to keep water out of your basement when the water is coming in through the foundation walls. It involves using waterproof membranes to seal the basement walls and keep water from penetrating the concrete. This approach, combined with a French drain system, is highly effective in maintaining a dry basement.
Interior waterproofing includes weeping tiles under the basement floor to route water to a sump pump or drainage. Interior waterproofing is ideal from ground water and is the only way to properly prevent seepage that comes up from under the floor and not through the walls. Both external and interior waterproofing can be just as effective as one another depending on how the seepage is coming into the basement. 

Before hiring a basement waterproofing company, it’s important to research and compare different contractors to ensure you find the best option for your needs. When speaking with waterproofing companies, be sure to ask about the written guarantee they offer for their work once the project is complete.

In an industry where some contractors operate out of trucks, having a waterproofing warranty is crucial to ensure your home remains properly protected. Unfortunately, many contractors cannot offer such a guarantee.

At DryShield Waterproofing, we provide a lifetime warranty on our services. We are so confident in the effectiveness of our external waterproofing system that we back our work forever. While some contractors may offer lower prices or faster service, this often comes at the expense of quality. In many cases, homeowners end up spending more time and money to fix poorly done work.

Many contractors mistakenly believe that simply keeping water away from your home is enough for basement waterproofing. The reality is that managing water around your home is essential to maintaining a dry basement, regardless of the amount of water in the soil. Proper drainage systems are key to ensuring that your home remains protected from water infiltration.
