Professional Waterproofing Protection for Roofs, Walls & More
At Precision Flow Gutters & Waterproofing, we provide professional waterproofing using our Precision Liquid Rubber system — a flexible waterproof coating designed to protect surfaces against water penetration, harsh weather conditions and everyday exposure.
Our liquid rubber waterproofing system creates a seamless protective membrane over the treated surface, helping to seal vulnerable areas where water can enter.
Whether you are dealing with an existing leak or want preventative waterproofing before problems start, we can assess the area and recommend the correct preparation and application method.
What Is Precision Liquid Rubber?
Precision Liquid Rubber is a flexible waterproofing coating used to create a continuous protective barrier over properly prepared surfaces.
Unlike traditional systems that rely heavily on joints and overlapping sections, liquid-applied waterproofing can form a seamless membrane across the treated area.
This makes it ideal for complicated roof areas, joints, flashings, parapet walls and other areas where water penetration commonly occurs.
Where Can Precision Liquid Rubber Be Used?
Our waterproofing system can be used on a variety of properly prepared surfaces and problem areas, including:
Concrete and slab roofs
Tiled roof problem areas
Parapet walls
Flashings
Roof joints and overlaps
Gutters and certain gutter joints
Waterproofed roof sections
Boundary and exterior walls where appropriate
Cracks and vulnerable water-entry points
Around pipes, outlets and roof penetrations
Every surface is different, which is why we inspect the area before deciding on the correct preparation and waterproofing system.
Our Liquid Rubber Waterproofing Process
1. Inspection
We inspect the area to identify visible cracks, failed waterproofing, damaged joints and possible water-entry points.
Finding the source of the problem is an important part of achieving a lasting repair.
2. Surface Preparation
The surface is cleaned and prepared before waterproofing begins.
Loose material, dirt, dust and failed coatings may need to be removed to create a suitable surface for the new waterproofing system.
3. Repairs & Detailing
Cracks, joints, flashings, corners and other vulnerable areas are repaired or reinforced where required.
Extra attention is given to areas where movement or water accumulation is likely to occur.
4. Precision Liquid Rubber Application
Precision Liquid Rubber is applied to the prepared surface to create a continuous waterproof protective layer.
Depending on the condition and type of surface, additional reinforcement or coats may be required.
5. Final Inspection
Once the application is complete, we inspect the treated areas and check that all critical waterproofing points have been properly covered.
Why Choose Liquid Rubber Waterproofing?
Seamless Protection
Liquid-applied waterproofing creates a continuous membrane with fewer vulnerable seams and joints.
Flexible Waterproofing
The coating is designed to remain flexible, making it suitable for surfaces exposed to normal expansion, contraction and weather changes.
Excellent Coverage of Difficult Areas
Liquid rubber can be applied around corners, flashings, pipes, joints and other areas that can be difficult to waterproof using conventional materials.
Weather Protection
Once correctly applied and cured, the waterproofing system helps protect the treated surface against rain and moisture penetration.
Preventative Protection
Waterproofing does not have to wait until a major leak develops. Treating vulnerable areas early can help prevent more expensive water damage later.
Waterproofing Problem Areas
Many roof leaks don’t necessarily come from the obvious area directly above the visible water damage.
Water can enter through a small crack or failed joint and travel before appearing inside the building.
Common problem areas include:
-Cracked parapet walls
-Failed waterproofing
-Roof joints
-Flashings
-Roof penetrations
-Concrete cracks
-Damaged sealing around -pipes
-Areas where water collects
-Ageing waterproofing -membranes
Our team focuses on identifying and treating the source of the water penetration, rather than simply covering the visible symptom.

Precision Liquid Rubber Maintenance & Warranty
Proper maintenance plays an important role in extending the lifespan of any waterproofing system.
Roof surfaces should be kept clean and drainage points should remain clear so that unnecessary standing water, dirt and organic growth do not build up.
Precision Liquid Rubber installations may qualify for up to a 10-year waterproofing warranty, subject to the approved application system, surface condition, maintenance requirements and the terms stated on your quotation or warranty documentation.
We will explain the applicable warranty and maintenance requirements for your project before work begins.
Frequently Asked Questions
How long does liquid rubber waterproofing last?
The lifespan depends on the surface, preparation, application, exposure and ongoing maintenance. A correctly installed and maintained waterproofing system can provide long-term protection.
Can liquid rubber stop an existing roof leak?
Yes, when the source of the leak is correctly identified and the affected area is suitable for liquid-applied waterproofing. Repairs and preparation may be required before the coating is applied.
Can Precision Liquid Rubber be applied over old waterproofing?
In some cases, yes. The existing waterproofing must first be inspected to determine whether it is stable and compatible. Loose or failed material may need to be removed.
Can it be used on concrete slab roofs?
Yes. Liquid rubber is particularly useful for waterproofing properly prepared concrete and slab roof areas, including joints, cracks, parapets and penetrations.
Do you waterproof tiled roofs?
Yes. We can treat suitable tiled-roof problem areas as part of a complete waterproofing solution. The roof must first be inspected to determine the cause of the leak.
Do you repair cracks before waterproofing?
Yes. Cracks and vulnerable areas are assessed and prepared before the waterproof coating is applied. Some areas may require additional reinforcement.
Do you offer quotations?
Yes. Contact Precision Flow Gutters & Waterproofing to arrange an assessment and quotation for your waterproofing project.
