How It Works

Our Process

01

Moisture Assessment

We identify all sources of water infiltration through visual inspection, moisture meters, and hydrostatic pressure analysis.

02

System Design

We recommend the appropriate waterproofing system — interior, exterior, crystalline, or drainage — based on your specific water infiltration pattern.

03

Substrate Preparation

All cracks, honeycombs, tie rod holes, and penetrations are properly prepared before waterproofing application.

04

Waterproofing Application

Waterproofing membranes, coatings, drainage mats, and drainage systems are installed per manufacturer specifications.

05

Drainage & Backfill

Drainage systems are installed and tested. Exterior systems are properly backfilled to prevent future settlement.

06

Verification

We test completed work and provide written warranties on all waterproofing installations.

Common Questions

Frequently Asked Questions

What causes basement water infiltration in NYC?▼
NYC basements experience water infiltration from multiple sources — hydrostatic groundwater pressure (especially in low-lying areas of Brooklyn and Queens), surface water infiltration through cracks, failing window wells, and deteriorated waterproofing membranes. We diagnose the specific source before recommending a solution.
What is crystalline waterproofing?▼
Crystalline waterproofing is a cementitious system that penetrates into concrete and permanently blocks water passage by forming insoluble crystals within the concrete matrix. It's an excellent solution for concrete basement walls and is self-sealing if new cracks form. We install Xypex and similar crystalline systems.
Should I waterproof from the interior or exterior?▼
Exterior waterproofing is the gold standard — it stops water at the source before it contacts the foundation. Interior waterproofing (including drainage systems and sump pumps) manages water that has already entered. Exterior excavation is not always feasible in dense NYC conditions, so interior systems are often the practical choice.
Do you waterproof parking garages in NYC?▼
Yes. We waterproof concrete parking decks and garage slabs using traffic-bearing membrane systems, joint sealants, and drainage systems. NYC parking garage waterproofing is a specialty service we provide across all five boroughs.
