There are interlocking male and female connectors along the edges of each roll. If using Grasspave2 for a large installation, you can save time by skipping this step or interlocking only periodically, as the established grass roots will anchor the product. We recommend using a deep rooting and hardy species such as Blue, Rye, Fescue, Zoysia or Bermuda depending on your area.

Grasspave2 works very well with seed or sod. To achieve the best results with sod, use a thin cut sod or rinse off any excess soil with a hose prior to installation, as excess soil will cause compaction and loss of porosity.

Hydrosourcing Seeding is most successful when a mulch is used. Avoid using mulch such as straw or pine as they generally do not retain enough moisture. Because sand never compacts it remains porous allowing the roots to thrive, providing an excellent medium for growing any vegetation. The addition of our proprietary Hydrogrow included with every order of Grasspve2 ensures water and nutrient retention at the base course level to expedite the root growth process after installation.

Grasspave2 exceeds H20 loading and has a psi of 15, so can support the weight of virtually any vehicle. This is why Grasspave2 has been the leading choice for porous fire lanes, utility and emergency access roads worldwide. While Grasspave2 is designed to withstand vehicular traffic, one must ensure that living grass gets enough sunlight, moisture and limited friction to protect its health.

For example, parking in the same spots or frequent passes over the same areas on a daily basis will cause the grass distress. However, Grasspave2 continually protects the root zone so even if the grass blades are damaged by overuse they will recover.

Yes, our second installation ever was a fire lane in and since then we have provided product to countless other cities and counties worldwide. It continues to be our most popular installation. Of course. Simply add a skid to the corners of the plow blades to raise them and proceed as usual. They may live in communities affected by heat waves and unseasonal rains that devastate their informal and poorly organized settlements.

Excluded from schools and with limited job options, facing xenophobia from the authorities and citizens, they often have no choice but to live in slums and informal settlements. Rainwater mixes with wastewater and in the absence of a robust sewage and sanitation system, stays in stagnant pools for months, exponentially increasing the risk of waterborne illnesses, such as diarrheal diseases. But packing up and moving is, if not impossible, then highly unlikely for the stateless. The high cost of moving and the risk of harassment and persecution outside their community of fellow stateless individuals make any move a potentially disastrous decision.

In Pakistan, there are millions of ethnic Bengalis, many of whom remain stateless. Noor is a member of the stateless Bengali community in Pakistan. Considered sympathizers with a hostile state, they may face harassment, hostility and even violence.

Among the poorest in the country, they reside in urban slums like Machar colony in the city of Karachi, a slum where sanitation systems do not exist with the exception of homemade informal systems developed by locals.

Diseases are rampant and health care is available only for those who can pay for procedures in private clinics. Noor asked that his last name not be used out of fear that the authorities could persecute him if he is seen as being critical: Criticism of the authorities can have serious consequences for those who are not considered bona fide citizens. Now in his late 30s, he has lived with his wife and kids in Machar colony all his life.
