Paver Pete demonstrates how to assess existing conditions and the steps to follow for a concrete porch overlay installation.
Options for the coping:
We used the Bullnose Grande to compliment the pool coping on this project. All options need to be elevated with adhesive to allow subsurface water to get out. Ensuring proper drainage prevents moss, weeds and efflorescence.
Options for the field:
Weeps in the masonry veneer:
Steps to follow
STEP 1: Install a foam cord, taped temporarily, along the wall to maintain a gap for water and air circulation.
STEP 2: Install coping with adhesive (see below for options) and use spacers to elevate it to have enough height to allow water to escape.
STEP 3: Install geotextile (we used Gator Fabric) over the porch and up the sides of the coping to prevent migration of bedding material.
STEP 4: Install the bedding material (see below for options).
STEP 5: Lay slabs on top of the pre-compacted bedding layer. The slabs should rest about 1/8 in. higher than the coping so water sheets off into the environment.
STEP 6: Apply the joint sand (we used Flexlock Ultra, the industry’s only overlay-specific sand).
STEP 7: Consolidate the joints by tapping them with a rubber mallet.
STEP 8: Activate the polymeric sand following the manufacturer’s instructions.
