Material Type
What is Laurenco Waterproofing?
It is a variety of cold applied waterproofing systems including a rubber modified asphalt system, a PMMA system, and a Laurenco deck system. These waterproofing systems are extremely durable and high performing, some projects have continued to perform over +60 years later without failure.
installation
How are Laurenco Waterproofing systems installed?
All systems are cold applied with the use of squeegees, rollers, or brushes.
installation, equipment
Do Laurenco Waterproofing systems require hot kettles or torches to install?
No, they do not require any flame or heat-based equipment to install. All Laurenco systems involve cold, fluid-applied products.
RMA System
What is the Laurenco RMA System?
Laurenco Rubber Modified Asphalt (RMA) system is a layered waterproofing system involving cold-applied, modified asphalt adhesive reinforced with modified asphalt sheet rolls.
Project Types
What types of projects can the Laurenco RMA System be used on?
It can be used for roofing, waterproofing, below grade foundations, planters, plazas, tunnels, blind-side waterproofing, split-slab waterproofing, and any projects with coal-tar pitch and asphalt contamination.
PMMA System
What is the Laurenco PMMA System?
Laurenco Poly Methyl Methacrylate (PMMA) System is a cold-applied waterproofing system involving a PMMA resin and catalyst used for roofing and waterproofing applications. It can be used as a stand-alone waterproofing system or in conjunction with the Laurenco RMA system.
Deck System
What is the Laurenco Deck System?
Laurenco Deck System is a layered, PMMA-based, cold, fluid-applied waterproofing system designed for use where fast return to service, extreme durability and performance are necessary. It is formulated to handle high vehicular traffic areas such as parking garages, plaza decks, helicopter pads, and more.
Negative Side Waterproofing
Can Laurenco Waterproofing systems be used on negative side waterproofing?
No, our systems cannot be used on negative side waterproofing
UV Stable
Are Laurenco waterproofing systems UV stable?
The Laurenco RMA system cannot be permanently left exposed to ultraviolet radiation. However, the RMA system can be configured to have a UV stable granulated cap sheet installed overtop or be integrated with the Laurenco PMMA system.
Roofing
Can Laurenco Systems be used as a roof?
Yes, the Laurenco RMA and PMMA systems can be used for low-sloped roofing installations. The Laurenco RMA can be used with IRMA roofing and conventional built-up roofing. The Laurenco PMMA system can be used for low-sloped roof waterproofing.
Concrete
Can Laurenco Waterproofing Systems be used on green concrete?
Yes, Laurenco products can be applied to green concrete. This helps speed job timelines along since our waterproofing systems do not have to wait for the industry standard of 28-day cures.
Concrete
Can Laurenco Waterproofing Systems be used on damp or wet concrete?
Yes, it can be used on damp or wet concrete without bulk water on the surface.
Substrate Prep
What kind of substrate preparation is required for Laurenco Waterproofing Systems?
Substrate should be typical, normal weight concrete free of protrusions, fins, depressions, and contaminants with a consistent broom finish surface profile.
Compatible Substrates
What kind of substrates with Laurenco Waterproofing Systems adhere to?
It can adhere to concrete, cement board, roof recovery board, plywood, steel, cementitious grout, surface prepared high-density polyethylene, and masonry.
Compatible Substrates
Is Laurenco Waterproofing Systems compatible with coal tar and asphalt residue?
Yes, it is compatible with coal tar pitch and asphalt residue. However, any damaged and delaminated and loose remnants must be removed.
Blind Side Waterproofing
Can Laurenco be used on blind-side waterproofing?
Yes, Laurenco can be used for blind-side waterproofing.
Fountains
Can Laurenco be used on fountains?
Yes, Laurenco can be used to waterproof fountains. However, the system must be protected from UV radiation.
Below Grade Waterproofing
Can Laurenco be used in contaminated below-grade conditions?
Yes, however, each project is different and must provide technical soil analysis reports to our technical department for review prior to any installation.
System Compatibility
Can Laurenco RMA system be used in conjunction with the Laurenco PMMA system?
Yes, the Laurenco RMA system is compatible with the Laurenco PMMA system.
Sidewalks, Walkway Waterproofing
Can Laurenco be used for waterproofing sidewalks and driveways?
Yes, it can be used in sidewalks, split slab, asphalt, and concrete driveways.
Approved Applicator
Do you have to be a certified, approved applicator to install Laurenco?
Yes, if a warranty is desired. Only trained and approved contractors can install and apply for warranties for Laurenco Waterproofing projects.
Approved Applicator
How do I become a certified approved applicator?
To become an approved applicator, reach out to a Laurenco representative to get a training lunch-n-learn scheduled. After an employee/crewmember has gone through the one-day training session, they are deemed an “approved applicator” and are eligible for our warranty program.
Approved Applicator
Where are training sessions held?
Training for approved applicators are held at our Medina, OH facility. However, on-site training can be arranged.
Warranty
What kind of warranties are available for Laurenco Waterproofing projects?
We provide three levels of warranty coverage for Laurenco Waterproofing projects: Bronze (material only), Silver (limited material, labor), and Gold (material, labor, limited overburden). To learn more about our warranty program, please review to our warranty page.
Warranty
How much do Laurenco warranties cost?
Each level of warranty has a different schedule of fees. Please refer to our warranty page for more information.
Purchasing
Can contractors and applicators buy Laurenco products directly from FBC Chemical?
No, Laurenco is strictly sold through building and roofing material distributors. However, we are more than happy to work with any preferred distributor.
FBC Chemical
Who is FBC Chemical?
FBC Chemical is the parent company to Laurenco Waterproofing products. For more information on FBC Chemical and its manufacturing divisions, please check out our website.
Pavement waterproofing
Can the Laurenco be used under asphalt pavement?
Yes. It can be used under a hot asphalt pavement but requires two layers of protection and correctly engineered asphalt by others.
Green Roofing
Can Laurenco be used in a green roof?
Yes. It is often used in green roofs and planters provided the correct root barriers and types of growing medium are appropriately designed and selected by the landscape design professional. It should be noted that some species of plants and trees are invasive, aggressive, and can be destructive to the waterproofing.
Water Containment Waterproofing
Can Laurenco be used in water containment configurations?
Yes. It can be used in water towers, fountains, water management facilities, and stormwater runoff containments.
