SIP Band Panel Placement

All of the foundation details show a layer of different soil material for the top 4 inches or so of finished grade. Along with adequate slope away from the structure (a building code requirement), some sources suggest an impermeable clay cap for this layer to further protect the foundation from water. This is a great detail for that purpose, but it is not a great one for establishing grass or other plants.

On the other hand, nothing should be planted within the first 18 inches of ground around the building perimeter anyway; this zone should be a mulched or pea-stone-covered free-draining zone. Best practice is to slope the site away from the building as much and as far as conditions allow and keep all vegetation back from the foundation.

There are a number of ways to create a "stop" right at the mud sill for termites trying to move up the foundation and into the above-grade wood assemblies. The most common are a metal flashing extends all the way across the mud sill and protrudes out like a drip edge, forcing termites to create a visible mud tube to get around the flashing. The other is a stainless steel mesh system called Termi-mesh. For more information on this system, go here:
