T caps are perfect for the inclement wet weather and harsh winters of New England and the northern states.

If Leakage and moisture penetration is caused by building movement or settlement with resultant “joint checking”, your stone caulk/sealant needs some assistance. Unknown building movement is among the primary causes of joint caulk/ sealant failure. To specify a particular caulk/sealant, owner/architect must determine the extremes of joint movement. Sealant manufacturers offer scribe kits to make these determinations and calculations.

Caulking/sealing a stone joint does not remove or compensate for movement or settlement of a building. It is suggested the interposition of T-Caps in caulked/sealed joints to take the abuse of such stress is in order; and the T-Cap being and adjunct to the caulk/sealant reduces the size of the opening of a joint to be caulked/sealed to assure improved, long lasting leak free joints.

Interpose T-Caps in your caulked/sealed joints. The selection of proper sized T-Cap is controlled by measurement of the joint opening to be caulked/sealed plus maximum percentage of joint movement experienced per scribe test plus 1/4 inch. The aforestated is the sum size of the outer dimensions of each T-Cap as installed.

T-Caps are a soft lead strip which when set and bedded in caulking compound/sealant, forms a cap which assures a permanent elastic seal for any masonry joint. After installation, the surface oxidizes rapidly to a neutral grey which blends with the masonry.
