Comprehensive Architectural Waterproofing Planning
About Taiwan Hydroseal BayBrane® Comprehensive Building Waterproofing Planning
Waterproofing for roads, railways, water routes, ecological bridges, tunnels, MRT stations, cross-harbor tunnels, cut-and-cover tunnels, roofs, balconies, court yards, basement roofs, car lanes, gardens, tree holes, landscape ponds, pools, drinking water tanks, etc.

Roofs・Balconies
Roofs and balconies, positioned at the
top of buildings, are exposed to rain
(including acid rain) and sunlight. This
exposure leads to thermal expansion
and contraction.

Swimming pools・Ponds・Water tanks
In earthquake-prone Taiwan,
reinforced concrete swimming
pools require waterproofing
materials that emphasize crack
resistance.

Bathroom・Toilet
Bathroom floors, constructed with
reinforced concrete (RC) plates or
metal decks, are susceptible to
leaks because of partition walls
and constant water exposure.

Kitchen
Effective kitchen waterproofing is
challenging and necessitates a
comprehensive plan due to the
variety of processes and materials
involved.

Outer walls・Window frames・Connection layers
Aluminum window edges embedded in concrete
with cement-sand joints are vulnerable to leaks
at weak points.

at weak points.
Courtyards・Landscapes
The courtyard, on the sunward side,
faces acid rain, thermal expansion,
tree root penetration, and chlorine
corrosion from pool water.
Driveways
Waterproofing at the 1F-B1F driveway
is one of the toughest areas to repair,
facing acid rain, scorching sun, and
constant load-bearing.
Basement • Elevator pit、Well point
During basement excavation, well points
lower groundwater if needed. Pumping
stops once the foundation slab's weight
exceeds buoyancy, and the motor is
removed. An iron plate is then installed
at half the slab’s thickness to resist water
pressure.

Basement • Interior and exterior walls, and Slurry walls
The slurry wall serves as temporary excavation
support and a permanent structural wall, bearing
soil pressure and underground rainwater infiltration.
Waterproofing is essential for safety and leakage
prevention.
Basement • Construction joints
The basement roof's load-
bearing beam and slurry
wall construction joints are
at approximately -2M on
the exterior wall GL. Water
seepage here is mainly from
surface water and rain.
