Reno Mattress Plus
Cost-effective riverbank hydraulic protection
Traditional riverbank protections, like rip-rap, require significant material due to imprecise placement and lack of confinement. Maccaferri’s mattress solutions—Reno Mattress Plus and RenoMac Plus—offer superior performance, reducing material use, costs, and environmental impact while ensuring durable and effective hydraulic protection.
Sustainable Engineering
Reno Mattress Plus and RenoMac Plus combine sustainability and performance. The PoliMac® coating ensures exceptional durability, even in the most aggressive conditions, reducing maintenance and extending the product’s life cycle. Rigorously tested, it does not release harmful substances into water. By using natural stone, these solutions integrate seamlessly into aquatic environments, enhancing biodiversity. With over 70% less material usage compared to rip-rap, they deliver the same performance with a lower environmental footprint.
Reno Mattress Plus
Invented in the 1960s, Reno Mattress Plus has been continuously improved through decades of research and testing. In collaboration with Colorado State University, we have perfected its performance to deliver unmatched hydraulic protection. By minimizing material consumption, it cuts emissions by over 80% compared to rip-rap, making it an ideal solution for sustainable riverbank protection.
RenoMac Plus
Building on the success of Reno Mattress Plus, RenoMac Plus delivers the same sustainability and performance benefits in a pre-filled solution. Designed for challenging underwater installations, it is ideal for quay protection and bridge foundations. Tested in partnership with Deltares Water Institute, it is the first and only solution validated specifically for quay protection applications.

BALLIMORE STORMWATER OUTFALL, NSW
Australia
Maccaferri Pty Ltd was approached by Rail Infrastructure Corporation (RIC) for design assistance on an energy dissipater for a stormwater outfall. The preliminary design was a reinforced concrete USBR (United States Bureau of Reclamation) style dissipater. With time and budget constraints against RIC, Maccaferri had to act quickly to deliver a solution for their needs. A further requirement for RIC was that the design had to be certified.

DIGOS-MAKAR ROAD
Philippines
The Department of Public Works and Highways implemented various infrastructure projects since the start of the new administration in 2016. The projects formed part of the administration's program called, "Build, Build, Build". In this, bridge construction and road widening works have been prioritized. In Mindanao, the DPWH Davao del Sur District Engineering Office allocated portion of its infrastructure budget to one of its most challenging projects to date - the rehabilitation and reconstruction of roads with slips and landslides along the Digos-Makar Road, a two-lane national highway in the mountainous portions of the city and is part of the Asian Highway, a network of highway routes of international importance within Asia and covers a total of 3,517 kilometers of roads in the Philippines. In order to achieve the rehabilitation and to upgrade the existing road to a four-lane highway as a minimum requirement for all Asian Highway-classified roads, the only viable solution at the moment was to build a retaining structure in the cliff side of the Digos-Makar road.

JUMEIRAH HOTEL MAS POOL
United Arab Emirates
M/s. Jumeirah Group appointed AK Design to develop the new MAS swimming pool at Al Qasr within the Madinat Jumeirah project in Dubai. The swimming pool is to be located on the open beachfront of the hotel. The Marine designer considered a return period of 1 in 100 years for the extreme design storm condition, and the client required a design life of 50 years for the pool. For the required 50-year design life, the 1 in 100-year storm event's probability is approximately 40%. The cross-shore beach response modeling studies revealed that the potential scours below the pool could be as deep as 2. 5m. Consequently, the pools' foundations must be designed to prevent lateral movement, settlement, and tilting of the pool when the beach sand is mobilized. The designer considered different conventional foundation protection options out of which secant pile option was recommended. However, the end client identified the following practical disadvantages with the secant pile wall solution; (1) Moderately costly (2) Significant disturbance to hotel guests due to noisy construction, (3) Heavy equipment required, (4) Reflects wave energy leading to beach scour and (5) Poor appearance when uncovered.
