WATERPROOFING OF TERRACES, DECKS AND BALCONIES

Flex A Seal’s waterproofing for terraces, decks and balconies (TDB) comprises of two distinct systems designed to satisfy the most diverse spectrum of construction methods.

Flex A Seal Composite TDB SYSTEM 1

DSCN1244

This system is generally applied to concrete floor structures or light weight structures on compressed cement sheet flooring. The installation of a graded cement screed is followed by the application of a reinforced, fully detailed, three-coat synthetic rubber waterproofing membrane. Tiles, pavers or tiling can be placed directly onto the membrane.

Benefits:

  • No mineral salt migration from the supporting graded screed to the tiled finish.
  • Maximum efficiency for tile installers as the substrates are accurately pre-graded and the waterproofing installation is professionally completed.
  • Flex A Seal’s waterproofing membrane installations are installed according to professionally engineering standards backed up by our in-house quality check system.

Flex A Seal Composite TDB SYSTEM 2

DSC00189This system caters for lightweight and solid constructed terraces, balconies or decks that require maximum protection due to extreme atmospheric exposure, built-up systems (e.g. roof gardens) or a variety of unique design criterions.

Flex A Seal’s composite TDB System 2 comprises of various reinforced and unreinforced, polymerised and pliable PVC sheet membranes. These are assembled using profiled flashings, angles, and preformed corners, and then joined by a welding process where each seam is progressively tested.

The system is typically installed onto a pre-graded substrate. Upturning terminations can be integrated to suit any wall finishes.

Flex A Seal teams install versions of this system that are loose-laid or adhered to the substrate. For exposed systems, we secure the membrane with concealed mechanical fixings during the installation to protect against the effects of possible “wind suction”.

Flex A Seal’s TDB SYSTEM 2 can be extended and incorporated as a continuous tanking system for swimming pools, retaining walls, or planter boxes.
