ABOUT MASSBLOC®

Engineered for strength, designed to alleviate hydrostatic pressure.

Discover the engineering excellence behind our Graviti® MassBloc® products, specifically designed to alleviate hydrostatic pressure while maintaining structural integrity. Learn how our innovative, permeable solutions enhance durability and performance in demanding environments.

Our core technology, Graviti® MassBloc® concrete MassBloc®, is engineered to be permeable at a tested water infiltration of 12,050 litres per m² per hour, allowing water to flow through while maintaining its structural integrity.

This innovative design reduces hydrostatic pressure behind our walls, which is a significant cause of retaining wall collapses, due to heavy rainfall and ground water flow. Graviti® MassBloc® concrete effectively diminishes these forces, ensuring stability and support for civil, architectural and residential foundations. Graviti® MassBloc® walls designed to ADR’s will withstand a traffic surcharge of 20kPa and higher while remaining permeable enough to let water pass through.

This advanced engineering solution protects vital structures from the detrimental effects of groundwater and rainfall, providing long-lasting durability and safety.

The dangers of unchecked hydraulic pressure Hydrostatic pressure can have severe effects on structures, especially retaining walls, foundations and basements. As water accumulates behind these structures, the increasing pressure can lead to cracking, buckling, or even collapse if not properly managed.

Effective design and the use of permeable materials are essential to mitigate these risks, ensuring the structural integrity and longevity of buildings in wet or flood-prone areas. 

Benefits

Discover the numerous benefits of Graviti® MassBloc® for your construction needs. Our permeable concrete MassBloc®’s are engineered to manage water flow effectively, reducing hydrostatic pressure and preventing structural damage. With enhanced drainage, improved stability and sustainable design, Graviti® MassBloc® offers a durable, cost-effective solution that minimises maintenance and maximises the longevity of your retaining walls and foundations in various environments.

01

Reduces Hydrostatic Pressure

Permeable Graviti® MassBloc® allows water to flow through, reducing hydrostatic pressure build-up behind retaining walls and foundations. This alleviates stress on the structure, 
minimising the risk of collapse. 

02

Prevents Water Accumulation

By allowing water to permeate through the MassBloc®, water is prevented from build-up behind earth retaining structures.

03

Enhances Structural Stability

Permeable Graviti® MassBloc®’s maintains structural integrity while managing water flow. They are fully reinforced providing the necessary support and strength, making them Ideal for earth retaining
structures.

04

Improves Drainage Efficiency

Graviti® MassBloc® enhances overall drainage efficiency by allowing groundwater to pass through, reducing surface runoff and soil erosion around structures. This promotes a safer and more sustainable environment. 

05

Minimises Maintenance Costs

By reducing water-related damage, permeable Graviti® MassBloc® 
eliminates the need for frequent repairs and maintenance, leading to long-term cost savings for Roads authorities Local Councils  and property owners. 
As well as enhancing overall durability. 

06

Supports Sustainable Construction

Permeable Graviti® MassBloc® contributes to sustainable construction practices by managing stormwater naturally. 
They help reduce environmental impact, promoting better water 
management and soil health in built environments. 

07

Retaining Wall Solutions Built with proven engineering expertise.

Gravity Wall Systems specialises in innovative retaining wall solutions, offering fully reinforced durable, customisable and permeable MassBloc®’s with approved 100 year Design Life designed to meet diverse construction needs with a focus on sustainability and long-lasting performance.
