Methods of Construction - Basements
When finishing a basement, or more particularly, any porous concrete surface, our first concern is protecting the finished product from moisture damage and water related incident. This stays as our top priority throughout the entire construction process, which is as follows:
Step 1: Approving with the customer that all concrete walls and floor surfaces are applied with DryLock© , to take the first step in preventing moisture from entering the new interior habitable space. The importance of this step is also to prevent hazardous molds and other bacteria from thriving in below grade moisture conditions. This step is crucial and should be applied by a painting contractor familiar with this product and its’ applications.
Step 2: The initial layout of this new habitable space, which has been previously approved by the customer, will be outlined by a metal track system designed to protect the base of the lumber from contacting the cement or any small amounts of moisture that my be residual prior to the DryLock© process. This track also serves as a guideline to provide a straight, level and true wall system which alleviates many problems with the sheetrock process later on.
Step 3: Begin framing throughout the new habitable space with Grade “A” Doug Fir lumber, either 2’x3’ or 2’x4’ and install top plates dead-on even with our corresponding bottom metal tracks, again to ensure for a straight, level and true wall structure. One of the reason we insist on using lumber, rather than metal studs, is that most basements are used for secondary kitchens, bathrooms or areas where home furnishings are needed to be hung safely and securely. This also serves as a very versatile method of framing by allowing easier access for future remodeling, if so desired, unlike metal studs.
Step 4: Install desired R-valued insulation and vapor barrier throughout all exterior walls to further reduce moisture penetration to provide an atmosphere that does not feel like a below grade living space. During this phase, all heating, electric and ventilation work should be performed by the corresponding trades.
Step 5: Sheetrock installation is crucial to the satisfaction of the customer insofar as the sheetrock and finished wall surface are what the customer will see everyday upon completion of the job. Seams on the sheetrock should be no greater than 1/8” as to provide for the maximum amount of expansion and contraction once taped and spackled. We always try and advise the customer of the benefits of sheet rocking the ceiling, in most applications, to limit the amount of air-borne particles which are able to penetrate into the space versus a drop ceiling, which is semi-permeable. In applications where a drop ceiling is absolutely necessary, we again provide a plastic barrier to reduce the penetration of air-borne particles. Esthetically the sheetrock ceiling gives the feeling of an above-grade living space.
Step 6: Taping and spackling. Although this is the least noticed work by the homeowner it is absolutely one of the most important steps. It is vital to have a seasoned tape and spackler to finish our product because it is the paintable surface and what the homeowner will see everyday.
