Sill Plate is a tough, versatile pressure-treated lumber. Like borate-treated lumber, it’s guaranteed to stop termites and prevent decay, plus it’s compatible with carbon steel (black iron) fasteners.
Both wood and concrete wick water well because they are porous materials. Pressure–treated bottom plates deal with the symptoms of the problem when a capillary break between wood and concrete deals with the cause. No direct contact, no need for pressure–treated bottom plates.
Similarly, is a sill plate necessary? A sill plate is not necessary but you still need some system to bolt/tie the house to the foundation.
In this way, what goes between sill plate and foundation?
- Lay a continuous layer of 1/4-inch foam gasket or similar moisture and air barrier on top of the concrete slab before applying sill plates.
- Apply a bead of caulk along the inside perimeter where the sill plate meets the concrete slab, if desired for additional air-sealing.
What is the difference between sill plate and sole plate?
Sill plate is PT lumber used on top of a concrete foundation on the bottom of a wall. Bottom plate is standard lumber on wood on the bottom of a wall. Sole plate is PT lumber on a concrete floor as used in a basement partition wall.
How do you keep water from going under a sill plate?
Extend the downspout several feet from the wall base to ensure all water sheds away. Next, applying a 100% silicone or urethane caulking along the sill or bottom plate/floor seam may prevent any water the gutters can’t handle from seeping inside. You should try to remove any latex caulking first.
Is a sill plate structural?
A sill plate (also called a sole plate, or simply a “sill”) is the bottom piece of wall structure where wall studs are attached. They are typically anchored to the foundation and serve as a very important component of all houses.
What size sill plate should I use?
A sill plate, also known as a sole plate, is the bottom horizontal part of a wall or building to which the vertical studs will be attached. Most sill plates are made from lumber – usually measuring 2″ x 4″, 2″ x 6″, 2″ x 8″ or 2″ x10″.
What is the purpose of a sill plate?
On most homes, the sill plate is the first piece of wood in the entire house, and it essentially anchors the house to the foundation. You can see the sill plate from the inside of your house if you look along the top of the masonry walls in the basement or crawlspace.

How do you fix a sill plate?
How to Repair a Rotted Sill Plate & Studs Lay plastic sheeting on the floor where you will be working to protect the floor and collect debris. Measure the 6-foot area of the sill plate that needs removed and mark it. Nail steel strapping pieces that stretch down from the top wall plate to each stud in the section being raised that is not being replaced.
How long will pressure treated 6×6 last in the ground?
The Forest Products Laboratory and other research groups have shown that treated wood stakes placed in the ground for more than 40 years remain rot-free. But young pressure-treated decks, many less than 10 years old, are being shoveled into landfills.
How do you seal a sill plate?
Air seal between the sill plate and the sub-floor with caulk, foam, or an equivalent material. Install a foam gasket beneath sill plates that are sitting on concrete or masonry and adjacent to conditioned space to both air seal and serve as a capillary break between the concrete and the sill plate.
Should I caulk sill plate?
Flexible foam sealant, designed for use on both wood and masonry, is the best type of caulking for sealing the sill plate. Latex caulking can harden and crack, and pure silicone caulking can pull away from the masonry if it becomes wet.
Does wood rot in concrete?
When wood is kept in direct contact with concrete, the moisture in the concrete will be drawn up into the wood, and after a period of time the wood will rot. when concrete is freshly placed it begins its drying process. when wood is in contact with the concrete, the concrete leaches out its water into the wood.
How do you install a sill plate?
Steps Order your wood. Cover the wood with a tarp. Measure the distance for the sill plate with a tape measure. Cut the length of board – use a handsaw or a circular saw. Place the cut board into position on top of the J bolts.
