How does MiraDRAIN work?
Each MiraDRAIN system allows multiple flow paths for water to pass freely into the drainage core, relieving hydrostatic pressure and protecting the waterproofing system. MiraDRAIN prefabricated drainage panels are lighter than traditional aggregate systems, making them less expensive to ship.
What MiraDRAIN 6000?
MiraDRAIN 6000 is a high-performance, high-strength drainage composite consisting of a three-dimensional, high impact polypropylene core, and a nonwoven filter fabric.
How do you cut MiraDRAIN?
MiraDRAIN can be cut with a utility knife or scissors. Slurries, shotcrete or concrete may be placed directly onto either side of the panels. The panels can terminate at the top of the footing and are flexible enough to form right angles to cover the top of the footing.
How do I install MiraCLAY waterproofing?
Install succeeding courses of MiraCLAY by overlapping the previous course a minimum of 4″ (100 mm). Stagger the seams a minimum of 24″ (600 mm). Install in shingle fashion so that the upper roll of MiraCLAY overlaps the lower roll. Fasten membrane once every 18″ (45 cm) on seams or as required to prevent blousing.
What is a drainage board?
Drainage boards allow water that has reached the walls of a structure to flow harmlessly away. Without drainage boards, water can saturate a building’s walls or pool around its foundation. The board is formed from an impermeable polymeric sheet, which is heated to form a dimpled drainage core.
What is a Mira drain?
MiraDrain are horizontal and vertical drainage composite mats. These multi-directional dimple board products are made to allow a continuous path for water to discharge, help eliminate hydrostatic pressure build up and to protect waterproofing systems.
What is bentonite in construction?
Bentonite is a type of clay that has an ability to swell and gel when dispersed in water which is used in construction mainly in excavation and foundation works. The word Bentonite is a toponym taken from a place called Fort Benton in USA, where it was discovered as a clay ore. Preparation of Bentonite Slurry.
What are draining boards used for?
A drainboard is a fixed platform attached to your kitchen sink. It allows water to drain into the sink while dishes are resting on it. It is a kitchen accessory that helps you to dry your dishes. The design of draining boards allows water to flow into the sink.
What is drainage board made of?
Made from high-density extruded polyethylene, the product has a series of dimples molded into the plastic that create an air gap between the membrane and the foundation.
What is Dimple board used for?
Dimple Board for Interior Drains protects against incoming water seeping from cove joints (where the wall meets the floor), concrete block or cracks in poured concrete walls. Placed on the footer, Dimple Board channels water beneath the slab and to the basement’s interior drain system.
How does a waterproof membrane work?
A waterproof membrane works by sealing a surface to avoid water leaks, chemicals, heat, and other substances from coming in contact with the surface underlay. It can withstand tear, breaking, and even releases water into the atmosphere as vapor to ensure a longer lasting structure.
How is the resting potential of the membrane created?
Ions move down their gradients via channels, leading to a separation of charge that creates the resting potential. The membrane is much more permeable to than to , so the resting potential is close to the equilibrium potential of (the potential that would be generated by if it were the only ion in the system).
When is the membrane potential 127 positive or negative?
When the c>sitive with respect to the ex- re current from the generator Ie neuron from the intracellu- , to the extracellular electrode membrane. As a result, the Chapter 7/ Membrane Potential 127 inside of the membrane becomes more positive while the out- side of the membrane becomes more negative.
How is membrane potential related to concentration gradient?
The electrical potential difference across the cell membrane that exactly balances the concentration gradient for an ion is known as the equilibrium potential. Because the system is in equilibrium, the membrane potential will tend to stay at the equilibrium potential.
Why is the membrane permeable to K + at rest?
Permeability refers to the ability of ions to cross the membrane and is directly proportional to the total number of open channels for a given ion in the membrane. The membrane is permeable to K+ at rest because many channels are open.
