Tapeta Track Resurfacing
Tapeta is a patented wax-coated mixture of sand, rubber and fiber that is impervious to weather and never turns to mud, and is the only system on the market today that has been tested over time to hold up under varied and severe weather conditions. The entire process of resurfacing the race track from ground breaking to completion took an estimated three months. The engineered track made Golden Gate Fields the eighth horseracing facility in the country to install the advanced racing surface. Tracks using the engineered surfaces have found them to be safer and kinder to horses in all kinds of weather.
Construction began on July 23. The inner and outer rails were removed as well as the backstretch fencing, to prepare for excavation. The next major step was the removal of of dirt surface from the main track and chutes. Earthmoving equipment was in the process of removing the old dirt track surface in preparation for the installation of the sophisticated drainage system and the layers of the new Tapeta surface.
With 15,000 cubic yards of old dirt removed from the surface of Golden Gate Fields main track, work began on the new conduit (storage for all the electrical and video wiring). These pictures shown here are the trenching taking place. The last picture is of the Bioswale, on the inside rail of the main track. The Bioswale is a landscape element designed to remove silt and pollution from surface runoff water. It consists of a swaled drainage course with gently sloped sides and filled with vegetation.
The next step in construction is the installation of the new rail. In the first picture crews are working on drilling holes for the posts of the the rail. Next, the posts are laid out on the track, spaced out to where they will be drilled into the ground. Finally, the posts are placed in the ground.
Crews have been installing perforated pipe for the draining system under the Tapeta surface. The trenching equipment, which can do up to 6,000 feet of trench per day, has made quick work of preparing for the the rows of pipe that encircle the track. The trenches, along with perpendicular ones that connect them, are lined with a geotextile membrane (filter cloth) and six inches of clean washed rectangular stone before the pipes are laid in place. The geotextile membrane will then be laid on the flat surfaces between the trenches and the entire surface will be covered with a layer of clean washed stone. Water hitting the Tapeta surface will filter through the porous blacktop and clean washed stone to be collected and carried away by perforated pipes.
The week of August 20, geotextile membrane (filter cloth) was placed over the underlying base of the track surface and a six inch layer of clean washed stone was added on top of that. The last picture is an aerial view of the race track, showing the completion of the clean washed stone layer.
The next step, now scheduled to get underway on August 27, will be the laying of a two inch layer of porous blacktop over the entire surface.
Crews began putting down the layer of porous black top on the track surface on Friday morning, August 29, starting with the home stretch. The first of the Tapeta Surface was added on Monday, September 17.
