Final answer:
The armouredstick HD base sheet lap joints can be effectively sealed using steel nails with rubber washers or by utilizing rocks and heavy objects to maintain placement. These methods facilitate proper sealing and ensure that the covers stay secured in areas such as soft rock terrain.
Step-by-step explanation:
The side and end laps of the armouredstick HD base sheet can be sealed using a variety of techniques. To ensure watertightness and secure placement, steel nails with rubber washers applied on reinforced eyelets are commonly utilized. Additionally, the use of rocks or other heavy objects can serve as temporary weights to help secure the covers in place, particularly in soft rock areas. The covers used in these methods are typically made from traction-resistant plastic tarp combined with a geotextile section, enhancing their durability. Furthermore, for applications involving chemical sustenance, such as with CS (Chloropicrin Sterilant) capsules, special refills made from PVC pipe with holes can be used under the covers, with their activation facilitated by moving rubber rings to expose the holes to seawater.
