Water intrusion is one of the most common causes of flooring system failure and structural damage in commercial and industrial buildings. A coating or flooring system installed over a wet or vapor-transmitting slab will fail — regardless of product quality. DTI provides waterproofing and moisture mitigation as both a standalone service and as part of a complete flooring installation, ensuring the substrate is protected before anything goes on top of it.
Most commercial waterproofing failures aren't dramatic leaks — they're slow. Moisture vapor transmitting through a concrete slab degrades adhesive bonds, blisters epoxy coatings, and causes resinous floors to delaminate from the substrate. By the time the floor shows visible damage, the problem has usually been present for months.
DTI addresses moisture at the source — through proper substrate testing, appropriate membrane or coating selection, and correct installation sequencing — rather than applying a topcoat over a problem and waiting for it to fail.
Concrete slabs emit moisture vapor at varying rates depending on age, mix design, and site conditions. High moisture vapor emission (MVE) rates prevent epoxy and resinous flooring systems from bonding properly. DTI tests slabs to ASTM F2170 (relative humidity) and ASTM F1869 (calcium chloride) standards, then installs the appropriate moisture mitigation system before any flooring is applied.
This is standard practice on every DTI flooring installation — not an upsell.
Basements, mechanical rooms, tunnels, and below-grade slabs are subject to hydrostatic pressure — water pushing through the concrete from the exterior. DTI installs crystalline and cementitious waterproofing systems that penetrate and seal the concrete matrix, providing long-term protection against hydrostatic infiltration.
Parking decks and exposed concrete slabs take the full impact of weather, vehicle traffic, and de-icing chemicals. DTI installs traffic-bearing waterproofing membranes — polyurethane and polyurea systems — that flex with the structure under load while maintaining a sealed, traffic-ready surface. Correct detailing at drains, expansion joints, and wall transitions is where most parking deck systems fail; DTI specifies and installs all penetration details as part of the scope.
Foundations, retaining walls, and below-grade exterior surfaces require durable waterproofing membranes to prevent long-term moisture infiltration. DTI installs fluid-applied and sheet-applied exterior systems appropriate for the exposure class and substrate condition.
For commercial and light industrial buildings with crawl spaces, encapsulation prevents moisture from migrating into the building envelope — reducing humidity, preventing mold growth, and protecting structural members. DTI installs closed-cell vapor barriers with sealed penetrations and perimeter drainage as required.
On every DTI flooring installation, substrate moisture is assessed before system selection. If moisture vapor emission exceeds the flooring system's tolerance, we specify a mitigation layer first. This prevents the most common cause of premature flooring failure in commercial and industrial environments — and it's included in our standard pre-installation process, not treated as a separate discovery after work begins.
If you've had a flooring system fail and aren't sure why, moisture is the first thing we check.
