No primer has been applied to this area—most likely because they ran out of primer and didn’t have additional supplies on site.
It’s critical to understand that there is a limited window for applying new primer over existing primer to ensure proper adhesion.
Not only that, we now have two areas where primer will be applied at different times, while the membrane will be applied across the entire area at once. Therefore, it’s essential to check the application timing and confirm it falls within the acceptable timeframe for both areas, in accordance with the manufacturer's specifications.
htmlText_7F92DB45_2278_6563_419F_958100F19452.html =
No sealant has been applied at the internal corners. Even if it were, the required minimum size of 12 mm has NOT been achieved.
Fillets like sealant or bond breaker tapes at internal corners are critical to the integrity of the waterproofing system. They help prevent membrane tearing at these stress points—particularly in the case of liquid-applied membranes.
It is essential to ensure proper installation and sizing of these fillets before applying the membrane.
A special gauge can be used to verify that the sealant size meets the required standard.
htmlText_8968B5CB_A664_4A66_41CB_C2376825F066.html =
Primer has been applied even though there are visible holes and inconsistencies in several areas, particularly between the blocks.
Additionally, shrinkage cracks are evident at the top of the block wall, and these have not been treated prior to membrane application.
All gaps, holes, and cracks must be properly filled with an approved repair product before any primer is applied. The membrane alone cannot bridge these defects — it will result in reduced or even no membrane thickness in those areas, creating potential points of failure.
It is important to note that if the substrate condition does not meet the minimum standards specified by the membrane manufacturer, the product warranty is typically void by default.
htmlText_2BE44D7B_189B_785E_4199_F02B712F89D6.html =
Sealant should be applied at all internal corners and along the top and bottom of the conduit, ensuring full coverage.
The applied sealant on each side of the adjoining elements must have a minimum width of 12 mm, as shown in the image below.
Note that applicators often spread the sealant, reducing its thickness—this is INCORRECT.
The purpose of the sealant is to eliminate sharp 90-degree transitions, as membranes are highly prone to failure at these angles, especially with movement. Spreading the sealant compromises its thickness and effectiveness in preventing membrane failure.
htmlText_87E617D1_A62B_D662_41E2_F67D037C7F6B.html =
There are two main types of concrete block walls: conventional blocks and H-blocks.
Conventional blocks are rectangular in shape, whereas H-blocks have an H-shaped profile that allows for continuous reinforcement and filling. While both types of walls are filled with concrete after construction, the key difference lies in the vertical joints. In conventional block walls, the gap between blocks often remains unfilled — especially when bricklayers fail to apply grout fully along the edges. This creates a significant risk for water ingress, particularly in wet areas.
In contrast, H-blocks are designed to cover the vertical joints with concrete, minimizing the risk of water penetration.
For this reason, H-blocks are strongly recommended for walls in wet areas, as they offer superior waterproofing performance compared to conventional blocks.
htmlText_78FBA9AA_2288_2521_41B8_CA86C7751ECE.html =
As you can see, there is localized damage to the block wall, which must be repaired using epoxy or grout before the primer is applied.
The repair product should be confirmed with the manufacturer to ensure compatibility with both the primer and the sealant.
The repaired substrates can be seen in the next image. However, the gaps at blockwork joints have remained untreated.
htmlText_4D623264_518C_D04F_41B6_28CD7031DDA1.html =
It should be noted that the membrane must extend up and over the vertical walls of the planter, in accordance with the relevant standards.

Since this is an underground application with long-term exposure to moisture, a more heavy-duty PVC conduit , as shown below in orange color, should have been used instead of this grey PVC, which is primarily designed for UV protection.
htmlText_4DFA3A56_5184_704B_41C6_5FF8686F9791.html =
The current installation of the conduits prevents any application of primer or membrane behind them, making effective waterproofing impossible.
To ensure proper waterproofing, conduits should be mounted on stand-off brackets. This allows for the correct application of primer and membrane behind the conduits, and for bond breaker to be applied around the bracket fixings.
htmlText_7EBECBBA_3D88_6521_41B1_AD155EE149FC.html =
The electrical conduits are completely disconnected, and instead of rectifying the issue before the membrane application, the applicator proceeded with the work—without raising any quetsions.
This shifts the entire risk onto the builder and highlights the fact that you cannot always rely on a subcontractor’s "20 years of experience" to ensure quality or accountability.
YOU MUST SUPERVISE THEM AND RAISE QUETSIONS.
htmlText_250E8BFC_18AB_B859_41B3_7921F0B86204.html =
The use of flexible corrugated conduits in wet areas is not a good practice. Not only the membrane can not be properly detailed around them, but they also experience greater movement, which the membrane cannot accommodate, ultimately leading to system failure.
htmlText_250E81E6_18A8_A869_41AC_15514B48EFD6.html =
There is a critical design issue here that increases the risk of water ingress outside the planter box. Planter boxes are constantly exposed to moisture and, during heavy rainfall, can remain filled with water for extended periods. Placing a penetration point near the bottom of the planter box significantly raises the risk of system failure at this location, potentially compromising the entire waterproofing system.
To mitigate this risk, it is good practice to position penetration points at a higher level, similar to how electrical penetrations are detailed.
htmlText_7F344433_2298_E327_4147_8F2434496360.html =
These abandoned holes must be fully rectified using an approved product and should not rely solely on sealant for waterproofing.
Sealants can degrade or detach over time, and since this is not a visible area, ongoing maintenance would be difficult.
It is recommended to first fill the holes with grout or epoxy, followed by applying sealant over the repaired holes and along internal corners.
htmlText_4DB67C95_5184_30C9_4179_B35F6AC7B74E.html =
This planter box is constructed from masonry blockwork. It should be noted that blockwork planter boxes are highly susceptible to waterproofing issues due to the presence of numerous mortar joints, which are prone to cracking and water ingress over time.
To ensure long-term performance and reliability, reinforced concrete (RC) walls should be used in place of blockwork. RC construction provides a continuous surface, reducing the risk of leakage and significantly improving waterproofing integrity.
htmlText_26080CD3_18A7_78AF_41B2_8750FA5F40EC.html =
As you can see, the drainage is located at the opposite end while this end is ponded, clearly indicating an incorrect fall direction.
Proper preparation is crucial—BOTH the fall direction and slope MUST be checked and, if necessary, corrected with an engineered screed before proceeding to application of any coatings.
Remember, no membrane can handle water ponding. It will fail....
