Building waterproofing for foundations and masonry.

Water that gets into masonry, foundations and the building envelope shows up later as stains, peeling paint and damage inside. We seal it out.

Where water gets in.

Water rarely shows up where it enters. These are the places we check first.

Foundation wallsBelow-grade walls take on ground water and show it as damp spots, white powder and musty basements.

Cracks and jointsMortar joints and hairline cracks in concrete and masonry let water travel into the wall.

OpeningsThe edges around windows, doors and penetrations are where water most often gets behind the surface.

Splash zonesThe bottoms of walls, steps and patios take rain splash and standing water every storm.

How we approach it.

InspectWe look for where the water is coming from, not only where it shows.
Clean and prepSurfaces are cleaned and loose material removed so coatings bond.
RepairCracks and failed joints are repaired before anything is sealed.
Seal and coatWaterproof coatings and sealers go onto the masonry, concrete or envelope.
FinishWhere it's part of the job, the area is painted to match.

Waterproofing and paint, together.

A lot of peeling paint is really a water problem. If moisture keeps coming through a wall, a fresh coat will blister and peel the same way the old one did.

Because we do both, the water gets dealt with before the wall is repainted, and the finish has a chance to last.

Building Waterproofing questions.

Something else on your mind? Call (508) 410-0974.

Why does paint keep peeling on my foundation walls?

Usually because moisture is coming through the masonry from behind. Paint alone won't stop it; the wall needs to be cleaned, repaired and sealed with a product made for masonry.

What is the white powder on my brick or concrete?

That's efflorescence: salts left behind as water moves through masonry and evaporates. It's a sign water is getting into the wall.

Do you waterproof commercial buildings?

Yes, along with homes. Tell us about the building and we'll come look.
