How does the BayBrane® waterproofing system form a protective layer?

From site assessment to professional application, build long-term waterproofing quality

BayBrane® waterproofing systemIt is not a single-material solution. It starts with site conditions, substrate testing, material setup, professional spraying, and final
inspection, Build continuous, stable, long-term waterproofing protection.

01

site Condition assessment

confirmleakage issues, building area, substrate condition, water exposure, and existing waterproofing condition.

02

Substrate testing

Assess surface condition, pull-off strength, and environment before application.

03

Material and method setup

Configure penetrating moisture-reactive primer, BayBrane® membrane, and local treatments based on site conditions.

04

Professional spray application

Dedicated equipment and trained applicators create a continuous seamless waterproofing layer.

05

Final inspection and reference verification

Inspection is carried out as needed and supported by roof, terrace, bridge, tunnel, and large-building references.

From system principles and material features to products and project cases,
understand the BayBrane® Durable Waterproofing System.

BayBrane® forms a continuous spray-applied waterproofing system over the substrate.

Hydroseal BayBrane® is a two-component spray-applied waterproofing system. It cures quickly after spraying and forms an orange-peel membrane with uniform thickness and non-sag performance.

The primer is a one-component moisture-reactive primer. It can be brushed, rolled, or sprayed, and penetrates concrete pores about 1–3 mm. In Taiwan's climate, it is usually ready for BayBrane® spraying in about 30–45 minutes.

BayBrane® waterproofing system key features

Fast curing, full adhesion, non-sag performance, and long-term durability make BayBrane® suitable for areas exposed to sun, rain, temperature change, and structural movement.

Elastic crack-resistant membrane

Helps accommodate substrate cracks and minor structural movement.

Full adhesion

Spray-applied installation forms continuous adhesion to the substrate and reduces hollow spots and weak points.

Non-sag performance

Can be sprayed on vertical surfaces or underside areas to improve application quality in complex areas.

Touch-dry in 3 minutes

Fast curing helps shorten waiting time and improve site efficiency.

Resists hydrolysis

Suitable for long-term wet or ponding-prone conditions.

Low pinhole risk on concrete

Sprayed application on concrete surfaces helps reduce pinholes and local leakage weak points.

Root penetration resistance

Suitable for courtyards, roof gardens, and planted areas that require root penetration resistance.
