Ajax Foundation Repair

Foundation problems can show up in many different ways.

For some homeowners, the first sign is a crack in a poured concrete basement wall. Others discover water after heavy rain, damp concrete blocks, deteriorated parging or a basement wall that appears to be moving inward.

Aquaphobia Foundation Repair provides professional Ajax foundation repair services for homeowners dealing with a range of basement and foundation problems.

We work throughout Ajax and the surrounding Durham Region and focus on identifying the actual source of the problem before recommending a repair.

If you’re dealing with a leaking crack, bowing wall, wet basement or deteriorating foundation surface, call 289-212-9326 or send us clear photos of the affected area for an initial assessment.

Foundation Repair Services in Ajax

Foundation repair is a broad term.

Not every foundation problem requires the same solution, and not every basement leak requires exterior excavation.

Aquaphobia Foundation Repair provides several foundation and basement repair services throughout Ajax.

Foundation Crack Repair

Foundation cracks are one of the most common problems we see in poured-concrete basement walls.

Some vertical cracks may be related to concrete shrinkage, while other cracks can develop because of movement or changing conditions around the foundation.

Even a relatively narrow crack can create a pathway for water.

If a crack leaks during rain or shows evidence of previous water entry, Ajax foundation crack repair may be appropriate.

For suitable poured-concrete cracks, polyurethane injection can often be completed from inside the basement without excavating around the exterior foundation.

Homeowners dealing specifically with a leaking wall crack can learn more about our Ajax Foundation Crack Repair service.

Water in a basement doesn’t always come from one obvious crack.

Potential sources can include:

  • Foundation wall cracks

  • Concrete block walls

  • Window wells

  • Foundation penetrations

  • Wall-floor joints

  • Exterior grading and drainage problems

  • Other weaknesses in the foundation system

The first step in basement waterproofing should be determining where the water is entering.

Some localized problems can be repaired from inside.

Other situations may require broader drainage or exterior waterproofing work.

The correct repair depends on the source of the water rather than simply applying the same waterproofing system to every basement.

Concrete block foundations can develop moisture problems differently than poured-concrete walls.

Instead of water appearing through one obvious crack, homeowners may notice:

  • Damp blocks

  • White mineral deposits

  • Peeling paint

  • Water staining

  • Moisture near the bottom of the wall

  • Musty odours

  • Larger damp sections after heavy rainfall

These conditions may indicate moisture travelling through the block wall or mortar joints.

Certain block-wall moisture problems may be suitable for interior cementitious waterproofing treatments.

Surface preparation is especially important because waterproofing materials need to bond properly to the masonry.

Paint, loose coatings or deteriorated material may need to be removed before treatment.

Learn more about block foundation waterproofing and the common causes of leaking concrete block walls.

Bowing Foundation Wall Repair

A basement wall should not noticeably bow inward.

Horizontal cracks combined with visible wall movement can indicate pressure against the foundation.

This is different from a simple leaking vertical crack.

Depending on the condition of the wall and amount of movement, carbon fibre foundation reinforcement may be an option.

Carbon fibre straps can be used in certain situations to reinforce and stabilize foundation walls without the large footprint of some other reinforcement systems.

More significant structural movement may require assessment by an appropriate structural professional.

Basement Floor Crack Repair

Cracks can also develop in concrete basement floors.

Some floor cracks are associated with concrete shrinkage and remain relatively stable.

Others may experience water entry, deterioration or movement.

The appropriate basement floor crack repair depends on the condition of the crack and what is causing the problem.

If you’re unsure whether a floor crack needs attention, clear photos of the affected area can often help determine the next step.

Foundation Parging Repair

Parging protects and improves the appearance of the exposed exterior portion of the foundation.

Over time it can crack, flake or separate from the underlying foundation.

Damaged parging does not automatically mean the foundation itself has failed, but deteriorating areas should be assessed before being repaired.

Aquaphobia Foundation Repair also provides foundation parging repair where appropriate.

Common Foundation Problems in Ajax Homes

Homes in Ajax can experience many of the same foundation and basement problems found throughout Durham Region.

Seasonal weather, heavy rain, freeze-thaw conditions, saturated soil and age can all contribute to foundation and moisture issues.

Common warning signs include:

  • Water entering during heavy rain

  • Vertical foundation cracks

  • Horizontal cracks

  • Bowing basement walls

  • Damp concrete block

  • White mineral deposits

  • Failed previous crack repairs

  • Water staining

  • Peeling paint

  • Cracks around basement windows

  • Basement floor cracks

  • Deteriorating exterior parging

Not every one of these signs means there is a serious structural issue.

However, repeated water entry, visible movement or worsening cracks are worth investigating.

Structural vs Non-Structural Foundation Problems

One of the most important parts of foundation repair is distinguishing between a waterproofing problem and a structural problem.

A vertical crack that allows water into the basement may primarily require waterproofing repair.

A wall that is visibly bowing inward is a different issue.

Simply sealing a crack does not correct structural movement.

Aquaphobia Foundation Repair focuses on identifying the type of problem before recommending the repair.

When a condition appears to require structural engineering input, the homeowner may need to consult an appropriate structural professional.

Many homeowners assume foundation repair automatically means excavating outside the house.

That isn’t always necessary.

For example, many suitable poured-concrete foundation cracks can be repaired using interior injection.

This can avoid disturbing:

  • Landscaping

  • Decks

  • Patios

  • Walkways

  • Driveways

  • Air-conditioning equipment

  • Other exterior features

Interior treatment may also be appropriate for certain block-wall moisture problems.

Exterior work still has an important role.

If exterior drainage, waterproofing membranes or other conditions need to be addressed from outside, excavation may be the appropriate approach.

The goal should be to choose the repair that fits the problem rather than automatically choosing the most invasive method.

TRANSFERABLE WARRANTY

Foundation crack repairs are backed by a transferable warranty, providing added peace of mind for current and future homeowners.

Details are explained clearly before work begins.

It was the best of times,it was the worst of times. A leak found in our foundation on the day of our open house. We chose full disclosure to all prospective buyers. I called up John at Aquaphobia. John asked a few poinent questions and reassured me that solutions were available. I sent a picture, and with a phone call, John provided a detailed description of the problem and the solution. John arrived at the agreed upon time later that day. Then proceeded to do exactly what he said he would do. He saved the day. With a warranty to stand behind his work we were able to redo the paperwork for the sale of the house and proceed. All at a fair price. A written receipt described the treatment and my real-estate agent was satisfied that we had done our due diligence. Highly recommend.

Jon was a tremendous help as we navigated a home inspection that required a foundation expert in very short notice. Jon rearranged his schedule to accommodate an evaluation/inspection the very next day after we spoke. His knowledge and experience was very helpful and gave us the piece of mind to purchase the property. Thanks again Jon!

Jon was guick to respond to my initial inquiry and gave good communication throughout. He also came out in a very acceptable timeframe to do the basement repair. The repair was done in the time window Jon provided and the work was completed to our satisfaction. Jon inspected the outside wall to ensure the crack was fully filled and he cleaned up also and left the basement area tidy. Would highly recommend.

I called aquaphobia on thanksgiving weekend after finding water in my furnace room. Honestly I wasn’t even expecting someone to answer the phone given that it was thanksgiving weekend, and I just planned on leaving a msg hoping they would get back to me. Nope, answered the phone and were happy to help. They got me to send them some pics of the situation and we went on from there. Super helpful, knowledgeable, patient, and friendly. 10/10 would recommend especially to new home owners
