New Construction Waterproofing Saves You THOUSANDS of DOLLARS? Don’t make the same mistake that 85% of uninformed homeowners make. 

waterproofing_concrete_wallsThe best time to determine your waterproofing needs is before construction on your home ever begins. Waterproofing your home is a very important but often overlooked process of new construction. There are many options available for waterproofing your home. However, there are few options that actually work and withstand the test of time.

In order to determine what will work best for your new home, you must first understand the difference betweenb damp proofing and waterproofing. A GOOD contractor will be able to explain the differences between damp proofing and waterproofing!

Note to Contractors – Please do not call us to Damp Proof a home as we will not have our name associated with this work.


New Construction Waterproofing vs Damp Proofing

Damp Proofing

  • Tar-based Product
  • Minimal resistance to standing water
  • Poor long term effectiveness
  • Lasts less than 2 years
  • Poor elongation

Damp proofing is a tar-based product that is applied to a building’s foundation walls and footing to deter water vapor from passing through the walls and into interior spaces. Damp proofing has little resistance to hydrostatic pressure (or standing water). Damp proofing will harden and crack in less than two years due to acids in our acid rain and lack of UV radiation which is necessary to keep tar pliable. When your home settles the tar will crack, exposing your concrete walls to water. The cost of damp proofing is less than waterproofing and hence is used more often. However, damp proofing is a very poor long term method for protecting your home and rarely lasts more than a couple years.


  • Modified Polymer Product
  • Excellent resistance to standing water
  • Excellent long term effectiveness
  • Lasts more than 30 years
  • Excellent elongation

Waterproofing is a modified polymer product applied to a building’s foundation walls and footing to prevent water from passing through the walls and into interior spaces. Waterproofing has excellent resistance to hydrostatic pressure and will stay pliable underground without UV radiation. The polymers in the waterproofing membrane keep acids in the acid rain from decaying the membrane. The waterproofing membrane will expand with your home as it settles. The cost of waterproofing is initially higher than that of damp proofing. As your home ages, the added cost of waterproofing is well worth the small price difference and pays for itself in a few years.


Major Components of Barrier’s Exterior Waterproofing System

  •  Modified Polymer Asphalt Emulsion (Membrane)
  • Insulating Drainage and Protection Board
  • Strip Drain and Footer Drain


It’s all in the MEMBRANE…

The Barrier Membrane is a costeffective, polymer-modified coating with excellent elastomeric properties. Engineered to meet or exceed the performance properties of the best polymeric waterproofing coatings. It has a thixotropic consistency and may be used on vertical as well as horizontal surfaces.


Benefits/Advantages of Barrier Membrane:

  • Spray applied for seamless application and penetration into substrate.
  • Crack spanning capabilities to resist hydrostatic pressure.
  • Allows for expansion and contraction on substrate without cracking or becoming brittle.
  • Applied to green (uncured) concrete walls immediately after forms are removed.
  • Applied to mortar as soon as mortar is dry.
  • Single-component compound – no mixing required – no human error.
  • Very rapid cure rates.
  • Environmentally friendly product that actually works.Compatible with a wide range of drainage, protection and insulation boards.

Note: We can give a warranty on the membrane by itself!


Insulating Drainage Board for a Lifetime of Protection

An insulating drainage board is recommended as a valuable addition to the waterproofing system. The board separates the membrane from the backfilled dirt around the home. For the average eight feet deep basement, the board will compress a mere 12% on average. Engineers estimate that it will take 300+ years for the board to become clogged and inoperable.


Benefits/Advantages of Insulating Drainage and Protection Board:

  • Protects Barrier membrane during backfill.
  • Provides an R-10 insulation value on walls.
  • Creates a permanent porous path of least resistance for water to flow.
  • Allows water to move vertically or horizontally.
  • Moves dew point from interior of home to outside by membrane.
  • Environmentally friendly product.
  • Excellent compressive strength.
  • Long term durable product.


Strip Drain and Footer Drain

The purpose of strip drains and footer drains are to create a permanent flow path around the footing of your home. These drains allow water to freely move around the perimeter concrete walls, keeping it from accumulating and standing against your foundation. The drains are run to a point lower than the footer to allow the water to naturally gravity feed around your foundation and flow to an area away from your home.

These strip drain and footer drain system consist of PVC drainage pipe and extruded HDPE with geo-synthetic filter fabric to strain out the fine particles that commonly block drains. To insure against future blocking, we will install one-clean out for every 75 linear feet of PVC drain pipe. We cover our drainage system with gravel and a filter fabric to give you the greatest possible water protection available today!



Barrier Waterproofing Systems offers a wide range of warranties that will surely satisfy the homeowner and possible future homeowners. Our warranties are transferable to new homeowners if the need to move should ever arise. This is yet another advantage of a value added Barrier Waterproofing System!
