Image
An anchor side plate is used to connect the concrete foundation to the sill plate from the exterior as part of a seismic retrofit when the sill plate is not accessible from the interior of the home
Image
Comprehensive above-grade water management details for a crawlspace foundation include a capillary break over the crawlspace floor, slope the surface grade away, installing gutters that slope away, and capillary break under sill plate.
Image
Correct seismic retrofit hardware for securing the sill plate to foundation wall
Image
Incorrectly done seismic retrofit, the plywood sheathing is not nailed to the mud sill and therefore it is not providing any shear strength
Image
Image
Right - A termite shield and a sill gasket are installed between the sill plate and the foundation on a raised slab foundation.
Image
Image
Right - Permeable rigid mineral wool insulation and appropriate water-management flashing details are integrated with new rigid foam siding to keep water away from the sill beam above the foundation wall
Image
Image
Right - Workers installed rigid foam on the floor and the sill plates of these pre-cast, pre-insulated concrete wall panels to provide a continuous layer of insulation under and around the not-yet-poured basement floor slab.
Image
Image
Right – Spray foam was installed at the sheathing intersection as well as the sill plate to sub-floor connection.
Image
Right – The sill plate was sprayed with foam prior to installation atop foundation.
Image
Image
Right – This wall is constructed with the sill plate overhanging the top of the foundation wall so that when rigid foam is installed on the exterior of the foundation wall, its surface will align with the surface of the wall sheathing.
Image
Seal the crack between the sill plate and the foundation wall
Image
Spray foam provides a critical seal between the subfloor, rim joist, and sill plate
Image
Termite shield is installed at the top of the foundation wall before installing sill plates; all seams and holes are sealed with epoxy
Image
The flat retrofit foundation plate is used to connect the concrete foundation to the sill plate from the exterior of the building as part of a seismic retrofit
Image
The flush cut method for seismic retrofit bracing of a cripple wall allows the plywood sheathing to be attached directly to both the cripple studs and the notched section of the mudsill
Image
The reverse block method for seismic retrofit bracing of a cripple wall uses a 2x4 attached to the sill plate to provide a means to attach the plywood cripple wall sheathing to the sill plate
Image
The universal retrofit foundation plate is used to connect the concrete foundation to the sill plate as part of a seismic retrofit
Image
This exterior wall retrofit permits drying to the exterior of a sill plate installed on an untreated flat foundation wall
Image
This exterior wall retrofit permits drying to the exterior of a sill plate installed on an untreated irregular foundation wall
Image
Vapor-permeable mineral wool insulation is installed on the exterior side of the sill beam during an exterior wall retrofit to allow the sill beam to dry to the outside
Image
With the nailed block method, wood blocks are attached to the sill plate and the cripple wall plywood is attached to the block to provide shear strength for correctly bracing a cripple wall in a seismic retrofit
Image
Wrong - The caulk is too far from the sill plate to effectively air-seal the gap.
Image
Image
Wrong – Foam was sprayed at exterior sheathing and sill plate connection, leaving gaps beneath sill plate.
Image
Wrong – It is not good practice to route plumbing through sill plates or on an exterior wall.
Image
Wrong – There is no foam gasket or air-sealing between the sill plate and masonry foundation.
