Concrete waterproofing is an essential key element in sustaining a waterproofed, leak-free structure. Once the concrete has taken its necessary curing time of 28 days, a waterproofing membrane coating must be applied instantly. During the curing time, all concrete structures begin to expand and contract with moisture; once formed, they immediately retain their structure from the initial pour state. All concrete waterproofing membranes carry sustainable factors of elongation, memory, thickness, and adhesion, making them ideal for rooftop waterproofing in Sydney.
As the leading waterproofing professionals in Sydney, Remseal conducts a free investigation prior commencement of any waterproofing membrane service.
Indeed concrete is found in many places across a variety of property types from floors, walls, rooftops in apartments and commercial buildings making concrete waterproofing an essential and important practice.
Types of Waterproofing techniques and materials that Remseal are experts in:
Concrete is often perceived as waterproof; however, concrete is naturally porous and can absorb moisture over time. Water can penetrate through capillaries, cracks, construction joints, honeycombing, and service penetrations, resulting in ongoing water ingress and structural deterioration.
Common causes of concrete waterproofing failure include:
Understanding why the waterproofing system failed is often more important than simply replacing the membrane.
At Remseal, we believe every successful waterproofing repair begins with a detailed investigation.
Before recommending a waterproofing solution, our specialists assess the source of water ingress and identify how moisture is migrating through the concrete structure.
Our diagnostic process may involve:
This diagnostic-led approach allows us to provide accurate repair recommendations and avoid unnecessary waterproofing works.
Concrete is one of the most widely used construction materials due to its strength, durability, and versatility. However, despite its solid appearance, concrete is naturally porous and susceptible to water penetration.
Without an effective concrete waterproofing system, water can migrate through pores, cracks, construction joints, and service penetrations, resulting in long-term structural deterioration and costly repairs.
At Remseal, we provide specialised concrete waterproofing solutions throughout Sydney designed to protect structures from water ingress, moisture migration, and hydrostatic pressure.
Not every leak requires membrane replacement.
Many concrete leaks originate from cracks, cold joints, and structural movement.
Remseal specialises in concrete crack injection systems designed to stop active water ingress and restore the waterproof integrity of concrete structures.
Depending on site conditions, repair methods may include:
These systems are commonly used in:
Many existing buildings cannot be waterproofed externally due to access limitations.
In these situations, Remseal can implement negative-side waterproofing systems from the internal face of the concrete structure.
Negative-side waterproofing is commonly used for:
These systems help resist moisture migration and hydrostatic pressure where traditional external waterproofing is not possible.
Below-ground concrete structures are constantly exposed to groundwater and hydrostatic pressure.
Without effective waterproofing, water can penetrate through cracks, joints and porous concrete, causing:
Remseal provides specialised basement waterproofing and below-ground waterproofing solutions designed to protect concrete assets from long-term water ingress.
With more than 43 years of experience, Remseal combines waterproofing expertise with leak detection, forensic investigations and remedial construction knowledge. Rather than simply installing membranes, our team identifies the cause of waterproofing failure and develops tailored repair strategies designed for long-term performance.
Our process follows five key stages:
This methodology allows clients to make informed decisions based on evidence rather than assumptions.
Water is one of the leading causes of deterioration in concrete structures.
When moisture penetrates concrete, it can contribute to:
Proper concrete waterproofing helps protect structural elements and extend the lifespan of the asset.
Whether the structure is above ground or below ground, a professionally designed waterproofing system is essential for long-term durability and performance.
One of the greatest challenges facing below-ground structures is hydrostatic pressure.
Hydrostatic pressure occurs when groundwater accumulates against a concrete wall, slab, or retaining structure. Over time, this pressure forces water through cracks, joints, and porous concrete surfaces.
At Remseal, we assess hydrostatic pressure conditions before recommending waterproofing solutions.
Our approach may incorporate:
Understanding hydrostatic pressure is critical to the success of any concrete waterproofing project.
We have the tools to locate and identify the main cause, and with our extensive experience we provide the best waterproofing solution that lasts.
