Reinforced Concrete Structures

The Newton Solution Sheets demonstrate the utmost level of waterproofing for reinforced concrete structures, while also highlighting the potential risks associated with inadequate waterproofing.

This specific type of structure, designed to exclude water and act as an earth-retaining structure, possesses two inherent weaknesses:

  1. Cracks may develop within the concrete due to insufficient compaction or water evaporation during the curing stage. This can create an intricate capillary network throughout the concrete. Applying an external Type A membrane can effectively safeguard against such imperfections.
  2. Non-compressed joints can facilitate the entry of water between the concrete joints, compromising the structure’s waterproofing integrity.

Download Newton Solution Sheets for Reinforced Concrete Structures

These downloadable Solution Sheets offer a glimpse into the wide array of waterproofing solutions available for reinforced concrete structures. They serve as a comprehensive waterproofing specification tool, encompassing crucial product details ranging from NBS Clauses to 2D and 3D CAD drawings.

Furthermore, these Solution Sheets have been evaluated and assigned a score on the Newton Waterproofing Index. This score reflects our expert assessment of the design’s likelihood to attain the necessary level of waterproofing.

Recommendations & Standards

Whenever feasible, we highly recommend opting for a new reinforced concrete slab designed according to BS EN 1992 (Eurocode 2). This slab should possess adequate mass and quality to withstand water pressure, as per the guidelines set forth in BS 8102:2022. By adhering to these standards, water intrusion should only occur at the joints, where the concrete is absent.

It is essential to ensure the overall structure is as watertight as possible. While cavity drain membrane systems can handle significant water ingress, it is beneficial to minimize such occurrences to prolong the system’s lifespan. Ideally, the system should primarily encounter seepage.

In situations where using just one form of waterproofing is necessary, a Type C specification proves to be the safest and most effective waterproofing design. This holds true for existing structures or alternative construction methods where implementing Types A and B waterproofing is not feasible.

The Newton Waterproofing Index

The Newton Waterproofing Index (NWI) represents an exclusive scoring system meticulously evaluating the risk and likelihood of success associated with various waterproofing specifications. These scores are assigned by a panel of seasoned specialists in waterproofing design, offering a reliable gauge of the potential success of each specification.

To gain a deeper understanding of NWI scores and how they can significantly assist your project design, we invite you to peruse our page elucidating the Newton Waterproofing Index and its functioning.
