Underlayment Coatings



Underlayment leaks happen all the time and are more vulnerable to leaks than systems that coat and protect the surface.  High End Development, Inc. does it all from installing our own flashings, door pans, waterproofing and concrete.  We have over 60,000 decks in service with no leaks!


We are approved waterproofing and sealant applicators of over a dozen product lines. This includes the industry's top single component systems such as Tremco 250 GC and their hot rubber products; Grace Deck-Prep; Pli-Dek UFinish. Our 2 component systems include Gaco Western and CIM. These coating systems provide a tough, long lasting waterproof membrane for decks, porches, walkways, and exposed corridors that will be finished with lightweight concrete.

Our experienced team  has the answers and the know-how to get your project done on time and on budget.



Gas & Vapor Mitigation

As the population increases in California, the need for space has forced builders to construct on top of land that otherwise would not be considered safe to build on due to contaminants in the soil.  Gas and vapor systems deliver a solution to the movement of chemical vapors or toxic gases found in the soils and groundwater.  These systems are developed to "cap" the vapor and gases in contaminated soils, mitigating the risk of any vapor or gas intrusion into the building.  

Our team has cultivated strong relationships with environmental soil engineers who can design an individualized solution for  your project requirement.  Our overall experience and knowledge in sealing the building envelope protects your building against dangerous gas and vapor from seeping into the building.  We install both a soil capping material and vent piping prior to slab pour. This method allows any vapor or contaminant to mitigate and protects your building from these harmful gases. 

High End Development, Inc. is the leading expert in gas and vapor mitigation.  We understand just how important capping these contaminant soils to ensure a successful, safe and vapor-free buildings. 

Don't risk the chance of soil contaminants leaking into your building - we can help!

Gas & Vapor Mitigation

Below Grade Waterproofing

Extreme climate conditions  or construction at the water table can pose complex and problematic challenges in keeping water and moisture out of your below grade project.  Water is under pressure below ground and  can force its way through even the smallest crevices in concrete.  This can cause water infiltration resulting in problems such as corroding the structure and damaging the building envelope.

High End Development, Inc. designs and warrants strategic installations with our manufacturers to protect your project's below-grade waterproofing systems from water intrusion issues.  This includes  sub-terrain levels, foundation walls, basements, elevator pits and tunnels.

We use products and installation procedures with durability and longevity!

Below Grade Waterproofing


Fluid-applied waterproofing systems are a great and effective alternative to hot rubber.  Cold fluid-applied products are safe and can be applied in conditions where hot rubber cannot.  Common areas of these types of systems include planters, private decks, under concrete, pedestrian walk areas and more.

High End Development, Inc. has over 15 years of cold fluid-applied installations and is an approved applicator for all the major fluid-applied products on the market today.  We understand the importance of a proper substraight  in order for these products to perform.  We offer  concrete prepping, power washing and  moisture checks to ensure the fluid-applied product of your choice bonds successfully.

Let us help you decide which product line works best on your project!

Fluid-Applied Waterproofing

Hot Rubber

Hot rubber is known as a high-risk application process due to the melting procedure known to cause injuries and fires.  Our installers are trained in proper usage of fire extinguishers, immediate first-aid and setting up your job site for optimal safety.  All employees are provided with the top of the line safety equipment to ensure your product is delivered.

High End Development, Inc. added hot rubber to our scope of work over 10 years ago We are certified to install the top product provided in our industry and with several million feet of hot rubber products in service that making us the industry's leading hot rubber applicator.


With every hot rubber application we contract on the job we proceed with extreme caution and attention to detail. Our specialty teams are trained in setting up your job site for optimal safety without compromising your schedule.

Hot Rubber


Injections are a solid remedy to existing concrete that needs repair or is leaking.  This method allows epoxy, grout or foam to be shot through pre-drilled holes into concrete, spreading out over the targeted areas behind the structure.  Upon contact with water, the system "gels up" to the water, creating a water-tight barrier.

High End Development, Inc. is the #1 source for injection 

​​projects in northern California.  We are Cetco, Grace and E-Pro's preferred injection applicator. In situations where

concrete needs to either be repaired or waterproofed where

excavation is not an option - we offer a wide range of services such as foam, chemical grout and epoxy injections.
