This is a picture of a spray foam insulation job we recently did in the Portland Maine Area. We sprayed closed cell foam in the wall cavities and on the ceiling. This room is being used for indoor agriculture which produces a fairly humid environment. Therefore, applying a vapor barrier product like out closed cell spray foam its a great choice. It helps to contain the moisture in a way that it can be transported out of the heated space via the duct work in the wall system.
We Now offer a full line of above grade and below grade waterproofing products in our Maine building market.
Below Grade spray applied water proofing membranes
Above Grade spray applied Air Barriers
Above Grade Spray applied Vapor Barriers
Rigid Board installation for above grade and below grade applications
In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents as well as protecting structural integrity. The waterproofing of thebuilding envelope in construction specifications is listed under “07 – Thermal and Moisture Protection” within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing material as well as waterproofing materials.
Walls are not subjected to standing water, and the water-resistant membranes used as housewraps are designed to be breathable to let moisture escape. Walls also have vapour barriers or air barriers. Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofingmembrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete. A potential problem in earth sheltered houses is too much humidity, so waterproofing is critical in these houses. Water seepage can lead to mould growth causing significant damage and air quality issues. Properly waterproofing foundation walls is required to prevent deterioration and seepage.
The penetrations through a building envelope need to be built in a way such that water does not enter the building, such as using flashing and special fittings for pipes, vents, wires, etc. Some caulkings are durable, but many are not a reliable method of waterproofing.
Also, many types of geomembranes are available to control water, gases, or pollution.
Over the past two decades, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials. Integral systems such as hycrete work within the matrix of a concrete structure, giving the concrete itself a waterproof quality. There are two main types of integral waterproofing systems: the hydrophilic and the hydrophobic systems. A hydrophilic system typically uses a crystallisation technology that replaces the water in the concrete with insoluble crystals. Various brands available in the market claim similar properties, but not all can react with a wide range of cement hydration by-products and thus require caution. Hydrophobic systems use fatty acids to block pores within the concrete, preventing water passage.
Sometimes the same materials to keep water out of buildings are used to keep water in, such as pond or pool liners.
New membrane materials seek to overcome shortcomings in older methods like PVC and HDPE. Generally, new technology in waterproof membranes relies on polymer-based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.
Waterproofing should not be confused with roofing since roofing cannot necessarily withstand hydrostatic head while waterproofing can.
The standards for waterproofing bathrooms in domestic construction have improved over the years, due in large part to the general tightening of building codes.
This was an interesting application where we sprayed an existing boat house. Originally there was only fiberglass insulation in this building. For building of this size that needs to be heated, the fiberglass was just not cutting it. The fiberglass was removed and replaced with our Icynene Proseal which has an R-value of 7.1 per inch.
DC 315: Certified Approved Thermal / Ignition Barrier over Polyurethane and Icynene LD-C-50 spray-on foams. DC 315 passed NFPA 286 and two UL1715 Room Fire Tests at the highest spread rate on the market. DC 315 passed five additional Ignition Barrier (AC 377, Appendix X) at an incredible 400 sq. ft. per gallon. DC 315 is the most cost effective ignition and thermal barrier option on the market, “One Coat, One Product Solution”Warnock Hersey Listed. DC 315 is a Green Product, VOC is Less then 50 g/l. What is truly amazing about DC 315, it applies as easy as regular latex paint and being a water base it cleans up in a snap. RECOMMENDED USES: This product is designed for use on interior polyurethane and Icynenefoam surfaces
USED BY: Schools, Colleges, Nursing Homes, Child Care Centers, Hospitals, Penal Institutions, Apartments, Hotels, Factories, Warehouses, Retail Stores, Restaurants, Utilities, Railroad and other Transportation Companies, Oil and Chemical Installations, Military Installations, and other facilities where fire retardant coatings are required.
Here are just a couple pictures of a recent job that we did in Portland, Maine. You can see how well the foam fills this fairly complex framing structure. This customer decided to use insulated panels on the wall and spray the roof deck with Icynene. Please let us know if you have any special applications for foam that you would like us to discuss. We have a large amount of pictures and there is a good chance that if it can be done then we have done it. We are happy to answer any questions you have through this blog or by phone call.
This picture shows a hybrid system with Icynene open cell in the walls and Sips panels in the Roof. This is a great system if you are building post and beam houses or you really want to preserve the existing roof in an old building like these.
These pictures show the steep incline of the road down to the camp. These pictures just don’t do the hill justice. We actually had to be pushed out by an excavator!
These Pictures show the two cottages that were sprayed.
On this job we decided to do a hybrid system. We sprayed our open cell foam to the attic floor. Then we sprayed the walls with closed cell. We did this because this is a metal building. The closed cell offers the rigidity and low vapor permeable material needed for metal buildings. However we were able to spray open cell to the attic floor which provided our customer with decent savings on the project because our open cell is less expensive.
