Mapei cements a tough bond with Mapeproof FBT
Mapeproof FBT by Mapei is a pre-applied
synthetic waterproofing membrane with a non-
woven fabric backing applied in full adhesion
to protect structures below ground level. It is
able to withstand up to 7 bars of pressure, and
provides Radon and Methane protection.
Mapeproof FBT is applied underneath
foundation slabs and against diaphragm,
pile walls, sheet piling and other permanent
retaining structures.
The waterproofing system is suitable for a
range of applications including basements,
garages, car parks, swimming pools, basins,
storage tanks, underpasses and underground
areas in general.
The fully-bonded waterproof sheet membrane
system incorporates two Mapei adhesive tapes:
Mapeproof FBT Tape, used to bond joints
between the upper-facing side of adjacent
membranes in the system, and Mapeproof SA
Tape, for bonding joints between the lower-
facing sides of adjacent membranes.
With extreme flexibility, Mapeproof FBT is
easy to install. The waterproofing membrane
is cold-applied (between +5°C and +35°C),
thus no heat or naked flames are required
on site. Positioned before placing the steel
reinforcement and pouring of the concrete,
joints can be bonded on horizontal or vertical
surfaces and shaped to follow the geometry of
the substrate, ensuring a longstanding tough
bond; due to its bond, Mapeproof FBT prevents
water from migrating laterally between the
foundation structure and the membrane, once
concrete has been poured. It does not require a
protective layer.
The certified Mapeproof FBT waterproofing
system also consists of two double-sided
adhesive tapes. Mapeproof Fix Tape is used
to hold the waterproofing membrane in place
during installation. Meanwhile, Mapeproof BA
Tape, a waterproof synthetic tape, is used for
treating fillet joints between horizontal and
vertical surfaces, as well as those between
adjacent vertical surfaces.

Modern barn
conversion gives
listed stone ruins
a new lease of life
The historic listed ruins of a former farm
estate property, dating back to the 19th
century, required sympathetic repair whilst
ensuring minimal disruption to the already
fragile structure. These partially collapsed
rubble stone walls had suffered from years of
weathering and deterioration but were now to
be incorporated into the annexe of a modern
farm conversion.
Flexible HeliBars were used to stabilise the
ruins as they offered the ideal solution due to
the irregularities in the direction of the mortar
beds. HeliBars were also suitable for reinforcing
the chimney breasts and fireplaces which were
important features to be retained from the
previous split-level property the ruins once were.
Once the concealed installation was complete,
the ruins were fully stabilised and reinforced.
The original materials were retained, structural
integrity restored and the ancient walls could
now be incorporated into the new annexe.
