Residential Construction Waterproofing

Associated Concrete Coatings provides a wide range of solutions for waterproofing new residential construction, serving contractors throughout NH and MA including waterproofing systems and weather barriers from Tremco, Tuff-N-Dri, Enviro-Dri and Horizon. 

  • Below-grade foundation waterproofing
  • Foundation coating systems, from spray to sheet membranes.
  • Exterior foundation waterproofing and damp-proofing
  • Retaining wall waterproofing membranes 
  • TUFF-N-DRI, Elastomeric, R3, R5, R10 insulation

Our waterproofing and damp-proofing products are water-based and meet stringent VOC-reduction requirements. Our award-winning exterior foundation and thermal foundation waterproofing systems may offer tax incentives for energy-efficient applications. Drain problems can be solved with less gravel and less labor. Our weather-resistant barriers reduce air infiltration through exterior walls while allowing vapor moisture to escape. These barricades prevent liquid moisture from penetrating your sheathing system without the use of staples or nails. Our permanent membrane will block water penetration conditions of even 200 mile-per-hour wind-driven rain. Systems include fluid-applied, spray-applied, roll on, and sheet membranes. Tar foundation waterproofing is a common name for these systems. Materials include polymer, elastomeric, rubber, HDPE-bentonite, bituminous, and asphalt based.

Prices for waterproofing exterior foundations for new home construction typically range from $.60 to $4 per square foot.

We can be onsite to install and apply waterproofing the day after removal of forms, or up to one week, depending on the product.

Tuff-N-Dri Basement Waterproofing System® is North Americas's number one brand of new foundation waterproofing. The powerful combination of Tuff-N-Dri H8 membrane and the thermal and drainage Warm-N-Dri board is key in insulating and minimizing condensation and water issues in the lower level of the home or building. Tuff-N-Dri H8 Foundation Waterproofing offers eight feet of hydrostatic head resistance while providing quick set up and consistent thickness throughout.

Watchdog Waterproofing H3 is a system that delivers great performance. With three feet of hydrostatic head resistance, Watchdog waterproofing is stronger, cures faster, and prevents sagging. This additional protection provides a consistent 40 millimeters of thickness throughout the coating process.

DrainStar® Stripdrain is designed to be used in combination with TUFF-N-DRI®, and WATCHDOG WATERPROOFING® products as a supplement or replacement for foundation drain tile and gravel systems.


ENVIRO-DRITM is a permeable membrane from Tremco that completely adheres to the sheathing. This effective seal stops water from entering while allowing vapor to escape. ENVIRO-DRI creates a more comfortable, energy-efficient home by preventing moisture-laden air from entering the house.

ENVIRO-DRI makes wraps, adhesives, staples, cutting, and material waste unnecessary. These penetrations or adhesive failure allows the water to get behind the protection, increasing the chance for future problems.


Horizon Foundation Finishing SystemTM from Tremco provides three levels of protection:

  1. Waterproofing membrane
  2. Fiberglass insulation board
  3. Durable, textured topcoat.

In tandem with the Tuff-N-Dri Warm-N-Dri system, the Horizon system meets the Energy Star requirement of achieving energy-efficient points. Horizon not only minimizes condensation in the lower level of the home but also greatly reduces heat loss, allowing for a more comfortable living space.
