Drainage

Sportag® is part of the Lytag® product portfolio and is a sustainable, lightweight drainage material used extensively on golf course fairways and greens as well as all other sports playing fields. Sportag® lightweight aggregate's shape and regular grading make it an ideal medium for land drainage applications. 

The Olympic Park's training pitch was built with Sportag

SPORTAG® 10X MORE HYDRAULIC CONDUCTIVITY

With Sportag®, the previously flooded Olympic Stadium training pitch became playable in just 7 weeks

Hydraulic Conductivity

Sportag® hydraulic conductivity is 10 times that of some natural aggregates (Sportag® = 1.6 x 10-1 m/s), thanks to a void ratio of 40% between pellets.

Advantages: Drainage rates vastly improved with Sportag®

Benefits: Facility will be available more often.

IMPROVED DRAINAGE

SportagTM helped improve drainage at Cowdray Polo Park

Attenuation

Sportag® has a 30% moisture retention. This allows moisture to be released at a constant rate, 15L per m2 @ 100mm depth.

Advantages: Allows for a more even and controlled release of water.

Benefit: Healthier, more consistent facility.

STRONGER ROOTS,
HEALTHIER SURFACES

SportagTM is used in the turf trays at Cardiff Millennium Stadium

Root Growth

Sportag® 40% void ratio improves aeration compared to standard aggregate, allowing roots to penetrate to greater depths.

Advantages: Stronger root systems.

Benefits: A healthier more robust surface.

VIRTUALLY NO REDUCTION
IN VOLUME OVER TIME

With little degradation or settling, SportagTM is a perfect bedding for pipeline

Stability

Sportag® innate strength of 6.5N, means there is very little degradation over time. Making it a perfect bedding for pipeline (UPVC, concrete, clay or any other thermoplastics) as there is no settling over time. 

Advantages: A constant volume is achieved with no subsidence.

Benefits: Very little long-term maintenance needed.

CARRY TWICE THE
VOLUME PER TRUCK

Logistics

An articulated truck can carry 36m3 of Sportag® compared with 18m3 of natural aggregate. More volume per truck reduces vehicle trips, haulage costs and environmental impact. 

Advantages: Quicker delivery to site.

Benefits: Savings in time and haulage costs; less environmental impact.

EASIER TO PLACE

Sportag® round nature makes placement easy

Placing and Handling

Sportag® is half the weight of normal aggregates, reducing the risk of manual handling injuries. Its round nature and strength allows easy placement in even the most demanding of locations.

Advantages: Quick and easy to install; no specialist knowledge or skills necessary.

Benefits: Reduces labour costs and time. Will not damage maintenance machinery.

Sportag® is perfect for all SuDS Systems

Sportag® can be used in permeable pavements

SuDS

Sportag® regular spherical shape, 6.5N strength, 40% void ration and 30% moisture retention makes it perfect for all elements of a SuDS System.

Including:
• Trenches
• Micro Trenches
• Soakaways
• Pipe bedding
• Permeable pavements
• Green roofs

Sportag® has a 30% moisture retention. This allows moisture to be released at a constant rate of 15 litres per m2 @ 100mm depth.

Land drainage

Summary
 
Compared to standard aggregare, using Sportag® in land drainage applications:
  • Gives up to 10X more hydraulic conductivity (SportagTM = 1.6 x 10-1 m/s);
  • Releases moisture quicker (15L per m2 @ 100mm depth);
  • Enables stronger root systems (a high void ratio improves aeration);
  • Has virtually no reduction in volume over time (ideal for bedding pipeline);
  • Allows twice as much volume to be carried per truck;
  • Is easier to place;
  • Offers improved drainage rates, strong plant growth and
  • Substantial cost savings.
